Fox Network Television History

The Fox Network television history has not all been plain sailing. It was launched in October 1986 after the parent company of 20th Century Fox, TCF Holdings, sold 50% of its shares to News Corporation for 0 million in 1985. New Corporation then bought six television stations in various major cities from Metromedia. At this time, the stations that they bought were broadcastings to just 22% of households in the United States. Once they started broadcasting as Fox in 1986 there were reaching 80%. This however, was not enough to be considered alongside the other three main networks of ABC, CBS and NBC who were reaching over 97%. Fox was still in its infancy at this point and although it had many plans in the pipeline it was only broadcasting one show - The Late Show Starring Joan Rivers.

The network was seen to have a young and slightly irreverent outlook in its programming and was soon broadcasting shows such as 'Married... with Children' and 'The Tracey Ullman Show'. It was not long before 'The Simpsons' was born and this went on to be the longest running animated series and situation comedy in the history of U.S. television. Fox Network television history was being made.

'America's Most Wanted' was the next big success story in Fox Network television history and was the first show to make it into the top 50 shows of the week in the all important Nielson ratings. The show is still among the prime time hits. Although Fox was well on its way to being recognised as a top network broadcaster, its ranking with the other big three was still elusive.

Fox Network Television History

This all changed in 1993 when Fox gained the National Football League coverage contract. Until then this had been the rights of CBS, where it had found its home since the 1950s. After just one season of the NFL coverage, Fox had to be considered alongside CBS, ABC and NBC... the big three had become the big four. Around the same time, Fox started to broadcast some soap operas aimed at the younger audience and these were popular from the outset. Shows such as 'Beverly Hills 90210' and 'Melrose Place' were an important part of the Fox network but even they were beaten on viewing figures by 'The X-Files'. This was the networks entrance ticket to the Top 25 in the Nielson rating schedule.

Since then, Fox Network television history has given us such shows as 'Family Guy', 'King of the Hill' and many reality shows such as 'Joe Millionaire'. Such shows are not popular with everyone and some have knocked the network for broadcasting distasteful viewing. However, the finale of the first series of 'Joe Millionaire' was watched by over 40 million people. The figures speak for themselves. Fox has always been an entertainment channel. It has never faired well with news reporting but has found its own niche where it entertains and brightens up the lives of millions of viewers throughout the United States.

How to Adjust Small Block Chevy Lifters

I got thinking and it came to me, I had never done an article on how to adjust small block Chevy lifters, so this article is going to make up for my transgressions of the past, I think people need to know this information if they have small block, or for that matter a big block Chevy.

I've written on almost every subject related to the restoration of a car, but never this subject, so please forgive me, and allow me to show you what I know on this subject, there is nothing illusive about adjusting the lifters on a small block Chevy engine, or for the matter a big bock either.

First of all if your installing a new camshaft, you should absolutely follow the recommendations of the camshaft manufacture, this article is based off of standard adjustment values and the camshaft that you are installing may be different.

How to Adjust Small Block Chevy Lifters

Things will change a bit depending on the type of camshaft that you have in your engine, you need to know a few things, first of all is the camshaft a solid, or hydraulic lifter version, solid lifters cams are also called flat tappet cams.

One good simple way to tell is to grab one of the push rods and push it down, if you can make the push rod move down, you have a hydraulic cam, a solid lifter cam you can't push the lifter down at all, once you have determined what lifters you have you can begin the adjusting process.

Of course this is all assuming that you have removed the valve covers, on a small block Chevy this is done by loosening the two bolts on the top of the valve cover, and the two bolts on the bottom, unless the valve covers are the new style with four bolts in the centre, then you need to remove them.

Tools You Need:
A 5/8 socket Ratchet Feeler gauges

You'll need the tools in the list above to adjust your lifters, the first thing you'll need to do is, if your adjusting hydraulic lifters you'll need to get the feeler gauge and unfold the one that says .030 on it, this is what you'll be setting the lifters to, if the cam is solid lifter get out the .026 gauge.

What your doing here is setting that back lash of your lifters to .030 if you have a hydraulic cam, or to .026 if you have a solid lifter cam, for this article we'll say that you have a hydraulic because they are the most common cams sold for street use.

So now that the valve covers are off of the car, you'll need to turn the crank of the engine until the two front valves on the right hand side are fully closed, and you must be absolutely sure that they are before you can begin to adjust them, or the entire job will be done wrong, this is very important.

They call this top dead centre, it's when the number one piston is at the top of it's stroke, and the timing line on your balancer is at the zero mark, this is the point where you can begin to adjust the lifters on the engine, I like to start out with number one just so I can keep track of where I'm at.

Now that you have number one at top dead center, you can begin to do the adjustment of the lifters, with the valves fully closed you need to take the feeler gauge and put it between the rocker arm and the valve stem, once you have put there it should feel a little stiff when you pull the feeler gauge out of from between the rocker arm and the valve stem, if should not slide easily, but should be a bit hard to pull on.

If it's not you need to loosen up the nut on top of the rocker arm with the 5/8 socket, and put the feeler gauge in between the valve stem and the rocker arm, and tighten it until it's seem a little stiff when you pull it out from between the valve stem and the rocker arm.

When your done adjusting the first two valves, you'd just move to the next two back and repeat the last two steps, you'd just repeat these steps until you have gone through all the valves on the engine, and wa-la your valves are now set perfectly.

NLP Eye Movement - A Powerful Technique in Neurolinguistic Programming

NLP eye movement or neurolinguistic programming eye pattern movements consist of a methods intended to determine whether an individual you are speaking with is kinesthetic, auditory or visual in his selected communication and learning approach. Every person has a specific choice regarding communication and learning though other styles can emerge on several occasions.

Aside from the three approaches, there is one more neurolinguistic programming eye pattern movement domain ñ the auditory digital. Among the four, it is not a preferred type. There are instances when your score comes out equal for the visual, kinesthetic and auditory but others still choose a specific domain like the visual. When that happens, an individual have more visual attributes rather auditory and kinesthetic attributes.

Now, written questionnaire which will help you identify a person's chosen style is not always available. Thus a quick visual evaluation for NLP eye movement is a perfect alternative. Make a fast and precise evaluation when you will personally speak with someone. Or, when you decide to talk with the respondent through email or on the telephone, you can combine words and phrases together with a mixture of visual, auditory and kinesthetic domain.

NLP Eye Movement - A Powerful Technique in Neurolinguistic Programming

When talking to your respondent, be very attentive of the language that he or she is using in order for you to determine their approach properly. Look for the specific neurolinguistic programming eye pattern movement when conversing with him or her, most especially when your respondent answers your inquiries. Identifying his or her style can indicate that you may fiddle with your language to make your respondent becomes comfortable talking to you.

Using the NLP eye movement patterns, it would be very beneficial if can create an immediate rapport with your patient. This way, the patient's reactions will be very spontaneous which will lead you to have an accurate assessment. So, when raising a question to your respondent, observe if he looks up before responding, if he does, he is on the visual domain. Or if your respondent stares sideways prior to answering, he is on the auditory domain.

You will know that your respondent is in kinesthetic realm of NLP eye movement pattern once he stares down to his right. This should be a major indicator that you should be alert about with your patients. This would indicate that the patient is in digital auditory domain when he stares down at his left side or on the area around the location of the heart. Responds are quick so be sure to be very attentive.

The Different Types of Programming Languages - Learn the Basics

The progression of computer programming languages was made possible by the programmer's search for efficient translation of human language into something that can be read and understood by computers. The languages generated, called machine code, have high levels of abstraction, which hide the computer hardware and make use of representations that are more convenient to programmers.

As programs evolve and become more sophisticated, programmers found out that certain types of computer languages are easier to support. As expected in a dynamic discipline, there is no standard for categorizing the languages used in programming. There are, in fact, dozens of categories. One of the most basic ways to categorize the languages is through a programming paradigm, which gives the programmer's view of code execution. Among the languages classifications according to programming paradigm are:

o Object-Oriented Programming Languages
Known as the newest and most powerful paradigms, object-oriented programming requires the designer to specify the data structures as well as the types of operations to be applied on those data structures. The pairing of data, and the operations that can be done on it is called an object. A program made using this language is therefore made up of a set of cooperating objects instead of an instructions list.

The Different Types of Programming Languages - Learn the Basics

The most famous object-oriented programming these days are C#, C , Visual Basic, Java, and Python.

o Structured Programming Languages

An exceptional type of procedural programming, structured programming provides programmers with additional tools to handle the problems created by larger programs. When using this language, programmers are required to cut program structure into small pieces of code that can easily be understood. Instead of using global variables, it employs variables that are local to every subroutine. Among the popular features of structured programming is that it doesn't accept GOTO statement which is usually associated with the top-down approach. Such approach starts with an opening overview of the system with minimal details about the various parts. To add these details, design iterations are then included to complete the design.

Commonly used structured languages include C, Pascal, and ADA.

o Procedural Programming Languages

Procedural Programming involves a list of operations the program needs to complete to be able to attain the preferred state. It is a simple programming paradigm where every program comes with a starting phase, a list of tasks and operations, and an ending stage. Also called imperative programming, this approach comes with small sections of code that perform certain functions. These sections are made up of procedures, subroutines, or methods. A procedure is made up of a list of computations that should be done. Procedural programming lets a part of the code to be used again without the need to make several copies. It achieves this by dividing programmatic tasks into small sections. Because of this, programmers are also capable of maintaining and understanding program structure.

Among the known procedural languages are BASIC and FORTRAN.

These are the different types of computer programming languages that you can consider when planning to make a computer program. Procedural programming splits the program's source code into smaller fragments. Structured languages require more constraints in the flow and organization of programs. And object-oriented programs arrange codes and data structures into objects.

History of the Media, Radio, and Television

When were the forms of media created? When did advertising first show up? Who owns the media?

Creation of the various forms of media

*

History of the Media, Radio, and Television

Newspapers & Magazines ~ 1880

*

Movies ~ 1910

*

Television ~ 1945

*

Cable Television ~ 1980's

*

Satellite Television, Internet, Digital Communication ~ End of the 20th century

In 1920, radio was first developed, primarily for use by the military, strictly for sendingHistory of the Media - Old Radios messages from one location to another. David Sternoff, the then-president of RCA, first had the idea to sell radio sets to consumers, or what were then called radio receivers. However, consumers needed a reason to buy radios, so RCA was the first to set up radio stations all over the country. Between 1920 and 1922, 400 radio stations were set up, starting with KBKA in Pittsburgh. Stations were also set up by universities, newspapers, police departments, hotels, and labor unions.

*

By 1923, there were 600 radio stations across the United States, and million worth of sets had been sold.

The biggest difference in radio before and after 1923 was that the first advertising was not heard on the radio until 1923. RCA at the time was made up of four companies:

*

AT&T

*

General Electric

*

United Fruit

*

Westinghouse

United Fruit was one of the first global corporations, and one of the first to advertise on the radio. The AT&T division of RCA first thought about selling time on the air to companies, which marked the start of "toll broadcasting." WEAF was the first station to operate this way, causing widespread outrage, and accusation of "polluting the airwaves."

Because of this controversy, the practice of selling advertising time was called "trade name publicity." Sponsors linked their name with a program on the air, rather than advertising a specific product in a 30 second "commercial" as we know it today.

Why did AT&T decide to experiment with charging companies for air time?

AT&T was not making any money from broadcasting at the time since they only made transmitters, not receivers. They only made money when new radio stations bought the equipment required to broadcast. They did not make money from consumers buying radios.

AT&T also started the practice of paying performers for their time on the air, rather than only volunteers, which was standard practice for radio content up until that point.

The first radio network

In 1926, RCA set up the first radio network, NBC. They decided it was more effective and efficient to produce shows in New York City, and then link the main radio station with stations all across the country, connected by AT&T (another RCA company) phone lines. (Now television networks are linked by satellite to their affiliates).

This was the beginning of the network affiliates system. The ideal network makes sure everyone in the country is capable of listening to their signal. NBC at the time had two philosophies:

*

Radio content was a "public service," whose function was to sell radios.

*

Radio content was designed to generate income from advertising.

History of the Media In 1927, the second network was formed. It was CBS, started by William Paley. Paley was the first to think that networks could make money strictly from advertising, not even getting involved in the sales of radios. Like AT&T, CBS did not make radios. From the start, they made their money from selling advertising.

The rising of radio networks caused the Radio Act of 1927 to be passed, which established the FRC, or what is now known as the FCC, to allocate broadcast licenses. The need for such an organization was brought on by the fact that airwaves are limited resources, and broadcasting itself is a scarce public resource. By the 1930's, the structure of radio have been set by the commercial format, although advertising never dominated radio like it would television later on.

In the 1920's and '30's, radio programs were divided into two groups. Sponsored shows, which had advertisers, and unsponsored shows, which did not. The radio station paid for the unsponsored shows. The sponsored shows, on the other hand, were created entirely by the company sponsoring the show; advertisers were totally in charge of the radio station's content. The content became advertising. Radio set the precedent for television, in that the same companies that controlled radio early on went on to control television.

Soon thereafter, television inherited the structure of radio. In the '40's, during the rise of television, RCA also held a monopoly on all television sets sold. By 1945-1955, advertising had taken over all of television. Television was organized around the premise of selling things. The entire television industry was creating a political atmosphere of suspicion and fear. Senator Joseph McCarthy, the founder of McCarthyism, which was based on the fear of Communism, and the HUAC (House Un-American Activities Committee, began to question people involved in television about their beliefs and associations.

What affected television in its early stages?

*

Politics (McCarthyism / HUAC).

*

Blacklists: From almost the inception of television, many writers, directors, and actors were considered to be pro-Communist and/or un-American.

Certain topics were totally off-limits at the time for television, particularly issues of race relations in the 1960's. Overall, networks were not happy with the political situation for television in the 1960's, both in terms of the blacklists, and of the fact that when every show had one sponsor, that sponsor controlled the entire program. Networks preferred to control the program, by way of moving to multiple sponsors/advertisers, where networks would retain control of the show, and advertisers would buy time in between the programming.

In the 1950's, networks decided to eliminate the practice of sponsors controlling the shows with a move to spot selling, or advertisements between programs, as we know it today. What caused the move to spot selling?

1.

Discovery of fraud in the quiz shows on television. Quiz shows were extremely popular at the time, and were liked by the networks, the sponsors, and the viewers alike. It turned out, however, that quiz shows were largely fixed. Charles Van Doren on "21" became a huge star due to his repeated wins, until it came out that the whole thing had been fixed. In the case of "The ,000 Question," the owner of Revlon was personally hand-selecting the winners and losers on the show.

2.

It was becoming financially difficult for just one advertiser to support an entire show.

Around this same time came the inception of ratings to measure a show's popularity. Ratings, quite simply, measure the number of people watching a show. To understand why ratings are so important, it's crucial to understand how the television industry works, through three questions, and their respective answers:

1.

Who owns television? [The networks]

2.

What is sold on television? [Viewer's time, not television shows]

3.

Who are the customers of television? [Advertisers, not viewers]

This might be a counterintuitive concept for some. The networks, which own television, areHistory of the Media - Old Television the buyers of shows, not the sellers. On the other hand, they sell our eyeballs, so to speak, to advertisers. Networks want the maximum possible profit from buying and selling time, both viewers' time, and advertisers' time.

The primary measure of television ratings, which determine the price of that time being bought and sold, is AC Nielsen, an independent company which provides information as to who watches what on television. Currently, about 4,000 households are used to represent the national viewing of television. In the 1980's, only 1,200 households were used. Some households have an electronic device installed on their television which tracks what they watch, while others keep a diary of viewing habits.

There are two measures for determining a show's audience. One is the rating, and the other is the share.

*

Rating: Percentage of total homes with televisions tuned into a particular show.

*

Share: Percentage of those watching television at a particular time who are tuned into a particular show.

The share is always greater than the rating. Ratings are more important for advertisers, and share is more important to the networks.

Example:

*

Total households with televisions: 150 million

*

Total households watching television at 8pm on Monday nights: 90 million

*

Total households watching American Idol at 8pm on Monday nights: 45 million

*

Therefore: Rating: 30, Share: 50

It's important to note how many factors can skew the results. Shows cost producers much more than the networks typically pay them for those shows. The way for producers to make money is by getting the networks to renew the show, in order to have a shot at making money from syndication on other channels, also knows as reruns. That is the case when individual stations (say for example, the Miami affiliate of ABC wants to carry Seinfeld), buy the rights to a show from the producers of that show. Shows that last only one season, for the most part, lose millions of dollars. One of the most important factors in whether shows will be renewed or not is their rating.

This brings us to how ratings can be skewed. For example, if a show has a 20 share, and it needs a 25 share to be renewed for another season, what might the producers do? In principle, they need to convince another 5% of the people watching television when their show is on to watch their show; this is no simple task, as that involves convincing millions of people. However, since the ratings are based on those 4,000 Nielsen households, that means that they could convince just 200 Nielsen households to watch their show, which would increase the share from 20 to 25. This is why Nielsen households must be kept totally secret from the networks. When the Nielsen households have leaked to the networks, one way which they got people to watch their show was by offering viewers a small sum of money for filling out a survey about a commercial which they were told would play only during a particular show. Since they had to watch that channel while their show was on, this would boost the share.

Once ratings are determined, advertising prices are set by two factors:

* The size of the audience.

* The demographics (income, age, gender, occupation, etc) of the audience.

In short, the job of television programs is to collect our time as a product, which they then sell to advertisers. Programs have to support the advertising, delivering viewers in the best possible state of mind for buying when the time for the commercials comes, which brings us to the Golden Age of Television.

The 1950's are considered the "Golden Age of Television." During this time, something called the "Anthology Series," where different actors each week took part in a show gained History of the Media - I Love Lucypopularity across the board...that is, with everyone except for advertisers. The anthology series format was not right for advertisers, as it covered topics which involved psychological confrontations which did not leave the viewers in the proper state of mind for buying the products shown to them between program segments. The subject matter of the anthology series was of the type that undermined the ads, almost making them seem fraudulent.

This brought up the question of what to network executives actually want shows to do? The answer is not to watch a program that makes them feel good, makes them laugh, or excites them, but rather to watch the television for a set amount of time. With so many new shows being proposed, standards began to be intentionally, or unintentionally, laid out for what shows could and couldn't do. Risks could only be taken at the beginning and/or end of shows. Laugh tracks were conceived to tell the audience when to laugh. Programs began being tested with audiences prior to being put on television and/or radio. Show writers now had to write shows that would test well.

Naturally, this caused many of the same elements and themes to appear in all shows. This was the beginning of recombinant television culture, where the same elements are endlessly repeated, recombined, and mixed.

This same culture is what perpetuated the idea that people watch television, not specific shows. While people certainly choose to watch certain shows instead of others, people less commonly choose to watch television instead of other things. People watch television. Regardless of what was on, television viewing rates were extremely stable.

How to Program a Siemens S7-300 Programmable Logic Controller

Do you have a Siemens S7-300 Programmable Logic Controller that you are not familiar with but you need to program it NOW! Following is a quick set of instructions I have put together to help you get started programming a Siemens S7-300 PLC.

After loading the programming software and connecting a Siemens MPI cable between your programming computer and the PLC, open SIMATIC Manager by clicking the icon on the desktop. The STEP 7 Wizard: "New Project" window will open. It is easier to use the Wizard to setup communications with your PLC, but I chose to take the scenic route. I figured I would learn more this way. So, close the STEP 7 Wizard window by clicking Cancel. If there are any other windows or projects open, close them. We want to start with a totally new program.

Create a new project by clicking the new project button on the toolbar in the upper left corner of your screen.

How to Program a Siemens S7-300 Programmable Logic Controller

The New Project window opens. Here you will see any existing programs located on your computer. Near the bottom of the window, you will see the Name: input form. Type whatever you want to name your new project and click OK.

A new window will open showing the name of your project at the top. You will also see your project in the window on the left hand side of the screen at the top. Right click your project and choose "Insert New Object". Choose the device you will be programming. We will be using the SIMATIC 300 Station so choose that selection.

You will now see SIMATIC 300 appear in the right window of your screen. It should be highlighted blue. Click anywhere in the window to make the blue go away. Double click SIMATIC 300 and it will move to the left window and "Hardware" will appear in the right window.

Double click "Hardware" and two (maybe three) new windows will open. On the left will be SIMATIC 300 - (the name of your project). The window on the right will be the catalog of parts.

Look in the right window, the parts catalog, and click the plus sign beside SIMATIC 300.

Click the plus sign beside RACK - 300. Click and drag the Rail onto the left window. You will now see the Slots window appear. This is where we will place our PLC components.

We will first choose our CPU. Looking at the parts catalog, in the SIMATIC 300 tree, choose the CPU that you are using. We are using the CPU - 300 so click the plus sign beside that choice.

Now look at the front top left of your PLC. This is where you will find the PLC model. I will use CPU313C-2 DP as an example since this is the model PLC that I use.

Find this CPU in your parts catalog and click the plus sign. You will now see some part numbers.

Look back at your PLC. Locate the door covering the MPI port. This will be the bottom left side of the PLC. At the bottom of the door you will find the part number. The part number for the PLC I am using as an example is 313-6CF03-0AB0.

Find this part number in the parts catalog. You will notice this is another folder. Open it and you will see V2.0 and V2.6. Look back at the PLC, open the door covering the MPI port, and right above the MPI port you will see V2.6.3.

Go back to the parts catalog and click V2.6. Notice how a slot in the left hand window will highlight green. I believe it will be slot #2. (Slot #1 is reserved for power supplies.) This is where you will drag and drop your CPU. (Notice the software will not let you put the CPU in any other slot but slot #2.)

When you release the mouse button over slot #2, a new window will open, "Properties - PROFIBUS interface". Click new, a new window opens, click Ok, and then click OK again. We are not setting up a network at this time.

You will now see your CPU and associated hardware listed.

Double click in the Slot that list your DI16/DO16 (Digital Input/Digital Output).

A window with three tabs will open. The first tab will be General, the second tab will be Addresses and the third tab will be Inputs.

Open the tab "Addresses". We need to change the default addresses. Do this by unchecking the System Default button and changing 124 (or whatever address you have) to 0. Do this for both the Inputs and Outputs.

We now need to change the Node Address. Go back to the window where you double clicked DI16/DO16 and double click in Slot 2, the CPU 313-2DP slot.

The Properties - CPU 313C-2DP window will open.

Look down the window a little over half way and find the Interface area and click on Properties. Another window, "Properties - MPI interface CPU 313-2DP" will open.
Change the address to meet your specific criteria. I know that my laptop, which I am using to program my PLC, is always addressed as 1 and my target PLC is usually addressed as 2. You will probably be the same.

Now click MPI(1) and click OK. Click OK again to close the Properties window.

Save and Compile by clicking the icon located on the left of the toolbar.

Download the hardware configuration to the PLC by clicking the download icon located on the toolbar.

A window titled "Select Target Module" should open. Click OK.

Another window titled "Select Node Address" will open. You should see listed your node address for the PLC you are working with as you configured it in a previous step. If not, click view and click on whatever node address appears and click OK.

Switch back to SIMATIC manager (by clicking the tab on the taskbar).

Click on Options. Choose Set PG/PC Interface. Choose PC Adapter (Auto).

Click Properties. A new window will open, displaying either Automatic Bus Profile Detection or Local Connection. Click Local Connection and choose USB. Now choose Automatic Bus Profile Detection and change the address to 30. You can check your connection now by clicking Start Network Detection. If a new window opens displaying Network Type = MPI, Transmission Rate = 187.5kbps, you have established communications with your S7-300. Click Close. Click OK. Click OK.

It is now time to start programming. Looking at the SIMATIC Manager window, click the plus sign located beside SIMATIC 300(1), click the plus sign beside CPU 313C-2DP, click the plus sign beside S7 Program(1).

Double click on OB1 and a new window will open named Properties - Organization Block

Here you can choose how you want to program, in LAD (ladder), STL (statement list), or FBD (function block diagram). Choose which you want to use and click OK.

Double click OB1 again and the LAD/STL/FBD programming window will open.

You can now start programming.
