Long before plasma set televisions made their appearance, people bought TVs for their size. The bulkier, the better and whoever got the biggest, meanest television screen won the game of one-upmanship with his neighbors.
And then picture quality came along. The game quickly shifted into whose TV made the grass look greener and Halle Berry better looking than she already is. These days, the gold medal probably belongs to plasma television sets.
Why plasma television set looks so good
If you have your old CRT (cathode ray tube) TV, you've probably been amazed at the technology that made pictures come alive through the screen. CRTs also use pixels or dots that when grouped together, form a bigger image. CRTs basically use a vacuum tube that fires electrons against phosphors. Three phosphors make up one pixel, which is made of red, blue and green colors.
The CRT technology has a measure of control on which phosphor group to hit and depending on the strength and length of the hit, the picture tube shows us an image with color and light contrast.
Now CRTs perform well and are in fact still popular in many parts of the world. The only drawback is that they are heavier, fragile and eat up a lot of living room space. You've probably noticed the same issues with your older computer monitors.
With a plasma television set, the technology is different. Gas inside a fluorescent light is excited to a degree and transforms into a plasma state. Pixels are still made with the same three basic colors, but since plasma can be aimed more precisely, more pixels can be hit to form an image. The result? A clearer, prettier picture on the television screen.
Not only is high resolution a feature that plasma television sets boast of, there are also the colors - all 16 million and more of them. Imagine watching the TV and knowing there are millions of different colors dancing right in front of your eyes even if you can only name a few. There's dragon red, leaf green, ocean blue or maybe canary yellow and egg white, but that's just a drop in the bucket of all the color possibilities that plasma television sets can offer.
The view from the other side
Another reason why plasma television sets win a lot of admirers is that it gives the concept of 'sitting in front of the television' a whole new meaning. Remember when kids used to fight for the 'best seats' right smack in the middle for TV viewing? This is no longer true with plasma TV.
With rear projection TVs, the viewing angle is about 45 degrees to the sides. A plasma television set can give you perfect images even at 160 degrees! You can walk from one side of the room to the other and you will still have the same picture quality, so don't worry too much about Aunt or Grandma sitting to the sides of the plasma television set. They are enjoying themselves just fine.
The flatness is also there for a reason other than giving the excellent viewing angles; it also reduces glare. With a plasma television set, you don't even have to dim the lights for better viewing. It works just as well even with ambient light turned to the max.
Issues and myths
No, you cannot refill your plasma television set's plasma content or that it's too radiation-heavy. Those are urban legends that are too silly to be even given a second look. Plasma television sets are a product of the latest technology and as such, still have a few issues here and there.
One of the most common is the burn-in issue, where a plasma television set develops a burned-in image when it's tuned in for too long to a static picture. There is also the half-life expectancy where plasma televisions are expected to burn a little dimmer after a few thousand hours.
These issues are quite true, but the real threat to the life and quality of a plasma television set is really a matter of wise and careful use. If you keep it on hours and hours on one channel with a static image, then a burn-in issue might emerge, but this will only happen after hours of day-in and day-out use. The half-life has also improved from the 30,000 hours (allowing you 9 years of plasma TV use for 8 hours of viewing a day) to 60,000 hours.
The Holy Grail of television sets?
For now, plasma television sets offer a lot to drool about but many would-be fans are put off by its price. Imagine paying about $2,500 for a 42-inch plasma TV. However, plasma televisions are priced that way for good reason - they offer tops in picture quality and contrast and even with the monstrous size some models are available in, you won't want a lot in the resolution department.
Getting a plasma television set instead of an LCD or some other high-def TV is really a matter of personal choice and budget. Shop for the unit that's perfect for you and enjoy all the other benefits you won't otherwise get had you made a different choice.

There can be little doubt that most of us have taken television for granted. After all it has been around as long as we have, and it is as common in our homes as electricity and running water.
None of us can imagine not being able to press a button on the remote control via cable or satellite and choose from among hundreds of televisions offerings at any given moment. Most of us have several of these receivers in our homes so our children can be appropriately entertained while we watch our important shows, like "As the World Turns", "Desperate Housewives", or "Survivor".
Couples can watch their own respective programs on different sets or activate Tivo to record any programs for later viewing.
The television story was much different in 1936 when on June 29th when the Radio Corporation of America (RCA) assembled every executive involved in RCA manufacturing and radio's National Broadcast Corporation (NBC) to view live television entertainment for the very first time.
Radio had flourished during the depths of the Depression and RCA/NBC were at the head of the class. These manufacturers and programmers of radio had successfully refined new dimension of sight to their broadcasting capabilities. The term "television" had been aptly coined for this since its literal meaning was "distant vision".
Seventy years ago on this June day, it was the hope of David Sarnoff, Chairman of RCA, to get all of their radio retailers, manufacturers and broadcasters involved expanding this new frontier of television.
The Empire State Building television transmitter was used to demonstrate high definition television (343 lines) to RCA's Licensees. The program featured speeches by Major General James G. Harbord (Chairman of the Board, RCA), David Sarnoff (President of RCA) and Otto S. Schairer (Vice-President RCA, in charge of Patents and Trademarks). This live broadcast included dancing girls and a film about army maneuvers. A dinner celebrating this event was held after the demonstration at the Waldorf Astoria.
Hence this was the world's first true TV Dinner! Note this is my discovery, no claims were ever made by RCA or NBC.
The only known surviving photograph of this private event known can be seen at: http://framemaster.tripod.com/index-3.html
The caption for this photograph reads:
"RADIO CORPORATION OF AMERICA
FOLLOWING A DEMONSTRATION OF THE RCA SYSTEM OF HIGH DEFINITION TELEVISION IN FIELD TEST INAUGURATED JUNE 29, 1936"
After this successful private broadcast it was decided to enhance the programming and invite the public and press to an even greater TV demonstration later in November. This time there would be live performances by professional actors, singers and entertainers.
The Birth of Live Entertainment and Music on Television, November 6, 1936
This is the true milestone in television history as all talent used for this broadcast were accomplished for the first time on live television. The following accounts are taken from the complete press release and photographs which I believe is the only complete one known:
"Experimental Television Demonstration For The Press
National Broadcasting Company RCA Building, Radio City, N.Y. November 6, 1936 TELEVISION DEVELOPMENTS DEMONSTRATED FOR PRESS BY NBC AND RCA
Television program transmission was demonstrated for the press today (Friday, November 6) by the National Broadcasting Company in a 40-minute program illustrating RCA experimental developments. The pictures were broadcast from the transmitter on top of the Empire State Building, and were received on the 62nd floor of the RCA Building.
David Sarnoff, President of the Radio Corporation of America, reported on results of field tests conducted by the company engineers since September 1 last. Lenox R. Lohr, President of NBC, discussed the practical problems presented in staging performances for the air.
The demonstration possessed four features not included in previous press demonstrations of television. It was the first made by RCA and the National Broadcasting Company for the press under practical working conditions, although previous demonstrations of laboratory television have been given. It represented the first showing of a complete program built for entertainment value as well as a demonstration of transmission. It also included the first showing of the new 12-inch receiving tube, which reproduces a picture on a 7 ½ by 10-inch screen. This is the largest screen yet employed which is capable of commercial adaptation.
A fourth feature of the demonstration was a television tour behind the scenes. By means of an especially prepared moving picture film, the guests were conducted through the NBC television studios in the RCA Building and the transmitter station at the top of the Empire State Building. The watchers in front of the line of receivers installed for the demonstration saw the processes whereby performances by "live" talent are transformed into pictures through the air, witnessed the scanning of moving picture films, and observed in detail the intricate television apparatus in actual operation.
Besides the talks by Messrs. Sarnoff and Lohr, and the behind-the-scenes film, the audience was entertained by the Inkspots (*The Ink Spots, see footnote), colored comedy teams, and Hildegarde, "The Television Girl," in characteristic songs. A Bob Benchley short and a selection of newsreel subjects also were demonstrated by television. The program was announced by Betty Goodwin, of the NBC Press Department.
The demonstration was presented and supervised by Ralph R. Beal, RCA Research Supervisor; O(scar) B. Hanson, NBC Chief Engineer, and Charles W. Horn, NBC Director of Research and Development. These engineers explained that numerous problems of transmission and production will still remain to be solved before television on a commercial scale can be attempted.
The demonstration was the first showing for the press of RCA experimental television under practical field conditions since the Radio Corporation of America assigned the task of setting up a television operating plant to the National Broadcasting Company.
This assignment included the construction of studios adapted to television technique, the installation of equipment in those studios and at the transmitter atop the Empire State Building, the determination of workable engineering methods for the transmission of the pictures, and the training of a staff to take over the operation of the plant.
Lenox R. Lohr, President of the National Broadcasting Company Talks about NBC's Television Future
November 6, 1936 Press Release from NBC Television
Lenox Lohr Statement For The Press
National Broadcasting Company RCA Building, Radio City, N.Y.
November 6, 1936
Statement by Lenox R. Lohr, President of the National Broadcasting Company, introducing Mr. Sarnoff at the NBC Press Demonstration of RCA Experimental Television:
On behalf of the National Broadcasting Company, I extend a cordial welcome to the representatives of the press who are assembled upstairs to see this television demonstration. What you will see today is the result of tireless effort on the part of many men and the expenditure of huge sums over a period of many years. The success of these efforts you can judge for yourselves. But, at last, television is out of the laboratory and into the field, undergoing tests which will assure that it does not reach the public until it is capable of satisfactory service.
The role of the National Broadcasting Company in television will be operating transmitters, programming, and, when it becomes available for commercial use, securing sponsors. In order that we may be prepared to do our part, our engineers are daily putting apparatus on the air under practical service conditions.
Our Program Department is learning an entire new technique in continuity writing, make-up, staging, and a multitude of other details which this new art will demand. It is experimenting with commercial programs to determine the effectiveness of television to sell goods.
Our engineers are studying the economics of networking, so that several stations may be interconnected by either coaxial cable of short-wave relays, and are developing equipment for the making of outside pick-ups. With the experience that we are gaining daily, we feel that when the time is ripe to offer television to the public, the National Broadcasting Company will be prepared to do its part. As you see television put through its paces here today, you will see results which are largely due to the vision and enterprise of Mr. David Sarnoff, President of the Radio Corporation of America, who will now speak to you.
TELEVISION STATEMENT TO PRESS November 6, 1936 by David Sarnoff, President Radio Corporation of America
In view of the public interest in the promise of sight as well as sound through the air, we have invited you here today to witness an experimental television test so that the progress in this new and promising art may be reflected to the public factually rather than through
the haze of conjecture or speculation.
You will recall that our field tests in television began only on June 29 of this year. That date marked the beginning in this country of organized television experiments between a regular transmitting station and a number of homes. Since then we have advanced and are continuing to advance simultaneously along the three broad fronts of television development-research which must point the road to effective transmission and reception; technical progress which must translate into practical sets for the home the achievements of our laboratories; and field tests to determine the needs and possibilities of a public service that will ultimately enable us to see as well as to hear programs through the air. On all these fronts our work has made definite progress and has brought us nearer the desired goal.
First and as of immediate interest, let me tell you the progress of our field tests. As you know, we have been transmitting from our television station on top of the Empire State Building in New York City which is controlled from the NBC television studios in the RCA Building. We have observed and measured these transmissions through a number of experimental receivers located in the metropolitan area and adjacent suburbs. The results thus far have been encouraging, and instructive. As we anticipated, many needs that must be met by a commercial service have been made clear by these tests.
We have successfully transmitted through the air, motion pictures as well as talent before the televisor. The distance over which these television programs have been received has exceeded out immediate expectations. In one favorable location due to extreme height of our transmitter, we have consistently received transmissions as far as 45 miles from the Empire State Building.
The tests have been very instructive in that we have learned a great deal more about the behavior of ultra short waves and how to handle them. We know more about interferences, most of which are man made and susceptible of elimination. We have surmounted the difficulties of making apparatus function outside of the laboratory. We have confirmed the soundness of the technical fundamentals of our system, and the experience gained through these tests enables us to chart the needs of a practical television service.
We shall now proceed to expand our field test in a number of ways. First, we shall increase the number of observation points in the service area. Next we will raise the standards of transmission.
In our present field tests we are using a 343 line definition. Radio Corporation of America and the radio industry have, through the Radio Manufacturers Association, recommended to the Federal Communications commission the adoption of 441 line definition as a standard for commercial operation. Our New York transmitter will be rearranged to conform to the recommended standards. That also means building synchronized receivers to conform to the new standards of the transmitter. Synchronization of transmitting and receiving equipment is a requirement of television that imposes responsibilities upon those who would furnish a satisfactory product and render a useful service to the public. On the one hand, standards cannot be frozen prematurely or progress would be prevented, while on the other hand, frequently changing standards means rapid obsolescence of television equipment.
Basic research is a continuing process in our laboratories not only that the problems of television may be solved but also to develop other uses of the ultra short and micro waves which possess such vast potentialities in this new domain of the ether.
While we have thus proceeded on the technical front of television, the construction and operation of television studios have enabled us to coordinate our technical advance with the program technique that a service to the home will ultimately require. Today, you are the guests of RCA's broadcasting unit -the National Broadcasting Company. Under the direction of its president, Mr. Lenox Lohr, the NBC has instituted a series of television program tests in which we have sought to ascertain initial requirements.
Ten years ago the National Broadcasting Company began a national service of sound broadcasting. Now it enters upon its second decade of service by contributing its facilities and experience to the new art of television.
One of the major problems in television is that of network syndication. Our present facilities for distribution of sound broadcasting cover the vast area of the United States and serve its 128,000,000 people. Similar coverage for television programs, in the present state of the television art, would require a multiplicity of transmitters and network interconnection by wire or radio facilities still to be developed.
Our program is three fold; first we must develop suitable commercial equipment for television and reception; second, we must develop a program service suitable for network syndication; third, we must also develop a sound economic base to support a television service.
From the standpoint of research, laboratory development, and technical demonstration, television progress in the United States continues to give us an unquestioned position of leadership in the development of the art. In whatever form such progress may be evident in other countries, we lead in the research which is daily extending the radio horizon, and in technical developments that have made possible a transmitting and receiving system that meets the highest standards thus far obtainable in field demonstration.
We are now engaged in the development of studio and program techniques that will touch upon every possibility within the growing progress of the art. The distinction between television in this country and abroad is the distinction between experimental public services undertaken under government subsidy in countries of vastly smaller extent, and the progressive stages of commercial development undertaken by the free initiative, enterprise and capital of those who have pioneered the art in the United States.
While the problems of television are formidable, I firmly believe they will be solved. With the establishment of a television service to the public which will supplement and not supplant the present service of broadcasting, a new industry and new opportunities will have been created."
*2:30 P.M. - NBC/RCA Television Demonstration. Ink Spots perform on the first live TV demonstration at NBC and, on the basis of this, are the first black performers to appear on television in the U.S. Variety states: "Later the Inkspots, a colored comedy - singing unit - put on a three-minute skit with all the stage makeup trappings. Couple of full-length showings were used here and the boys were in motion besides. It worked out okay." (Since they are the first performers mentioned in the article, the Ink Spots may have been the first performers of any color to perform on TV in the U.S.) [Variety, 11-11-36 & New York Times, 11-7-36
Steve Restelli created the website HistoryTV.net in 1999 to share some of his photographic collection of eary experimental television over the internet for students, scholars and other history buffs. Since that time he has both expanded his collection and been used as a resource for authors and others who really want to view some of the earliest television images that survive. Much of the collection was once owned by Dr. Vladimir Kosma Zworykin, who is often credited as one of Televisions inventors.

The Invention of Cable Television & Alternatives to Cable TV
There are many claims to the first CATV system, but only one thing is for certain; it originated in the United States and, according to one famous recollection, cable television had its beginning in 1948 in Mahanoy City, Pennsylvania. Community antenna television, as it was then called, was invented by John and Margaret Walson out of a necessity to bring television to their customers. They owned The Service Electric Company, a company designed to sell, install, and repair appliances. When they started selling television sets in 1947 their Mahanoy City customers were reluctant to buy because of reception issues. This particular region of Pennsylvania had difficulties picking up the stations in nearby Philadelphia due to the mountains that surrounded them.
To solve this problem, Walson installed an antenna on a utility pole that he placed on a local mountain top. It allowed him to demonstrate that the televisions could pick up good broadcasts coming from some of the Philadelphia stations using modified signal boosters and cable to connect the antenna to his store. So, in 1948, he charged a small fee and connected the antenna to several of his customers' homes as well, marking the beginning of the cable television business.
The early 1950s saw further development of the cable system. By then, the FCC had released its hold on a three year long freezing of new television station construction and had "assigned a nationwide television broadcasting plan", leading to the fairly rapid development of new television stations. Department stores began to encourage television viewing by displaying several different models for sale. Of course, this meant that television antennas had to also be sold. At the time, each home or apartment required its own antenna, creating a somewhat unsightly "forest of antennas" on the roofs of some apartment buildings.
This prompted Milton Jerrold Shapp to create a system that used only one master antenna for an entire building. He did so using coaxial cable and signal boosters, enabling the cable to carry several signals at once. Not too long after that, another appliance store owner experiencing the same problem as that of the Walsons read about Mr Shapp's system. Figuring that, if it could work for apartments and department stores, it could work for an entire town as well and he set up the first cable television system similar to how we know it today.
Because of Mr Shapp's innovative new system, television spread like wild fire throughout the country, enabling remote and rural areas to receive a signal and "by 1952, 70 'cable' systems served 14,000 subscribers nationwide". But, of course, people would not remain content with allowing the cable system simply to be used as a means of providing better signal strength to rural areas.
Toward the end of the decade, cable operators began using technologies to pick up signals from stations hundreds of miles away, irreversibly changing the way the cable and television industry operated. This new found ability to import more signals from distant stations also allowed for more programming choices. Now, the cable systems that only allowed for three channels (one for each network) soon changed, allowing room for seven or more channels due to the fact that they could pick up programs from distant independent stations (2). This created more interest in cable as a provider for city television as well because of the variety in choices it allowed.
By the early 1960s there were nearly 800 cable network systems in business. Many of these cable network companies started expanding into multiple cities, causing the beginning of the multiple system operator (MSO). Yet, the local broadcasters were afraid of the competition that cable companies were creating so they asked the government to stop the importation of signals by cable companies. The freeze that the Federal Communications Commission (FCC) placed on the importation of cable signals lasted until 1972.
In 1972 the service channels that people pay an extra premium for were started when Service Electric began to bill for Home Box Office (HBO). It had a minimal beginning with about a few hundred viewers the first night. However, it has become one of the largest pay cable services around. It is because of its success that so many others have followed.
In addition, the craving for more channels led the FCC to issue a rule in 1969 that required "all CATV systems with over 3500 subscribers to have facilities for local origination of programming by April 1, 1971". Furthermore, in 1976, the FCC decided to require that new systems must have more than 20 channels to choose from and that cable providers that had more than 3500 must provide public channels for education as well as government access.
Thus, cable television has been divided into two different services: basic service and premium services. Basic cable generally includes the local television networks and a few other common channels that are not transmitted with any type of encryption method while premium channels scramble their signals. They include channels such as HBO, Cinemax, Showtime, and Starz and are generally paid for in various extra packages in addition to the basic service.
The fees for service, whether basic or premium, did not defer customers and by the 1980s the major three television networks (ABC, CBS, and NBC) had all but lost their monopoly on viewers. "The era of network television" was coming to an end. Even other news networks began to emerge. "By 1985, 68% of all American households (60 million) had cable television service" . Cable News Network (CNN) first appeared on the scene in 1980.
With the emergence of all the new cable networks, cable television revolutionized the way Americans viewed television, and inspired many more changes yet to come. The invention of the VCR and, still later, the DVR would follow suit, yet again changing how American's use their televisions.
In recent years technology has begun to produce alternatives to cable television. As internet content grows to out weigh what cable TV services can offer. Many people have begun to migrate from cable television to Internet television. (24% in the US, 40% either use Internet TV alone, or a combination of Cable and Internet TV together) Internet TV provides the user with an opportunity to view all their favorite programming, most commercial free, in High Definition and directly to the users television. Internet TV. Internet TV has the potential to replace cable television as the preferred method of home entertainment delivery.
Savings and selection are mentioned as the primary reasons to switch to a Cable TV alternative. The average monthly cable bill in the US is between one-hundred fifty and two-hundred dollars per month. Internet TV in comparison has a one time fee for the home component and no additional monthly viewing fees. Users who wish to use services like Netflix and Blockbuster online may now watch movies directly on their HD television. Internet TV does not bypass legal means of content delivery, you must still pay the fees associated licensing fee for movie rental sites like Netflix and Blockbuster.
Free Internet TV content currently licensed for viewing online in high definition. (Short list) All programming from the major television networks; ABC, NBC, CBS, FOX, most cable networks (CNN, E!, etc) also broadcast their programming online for free. Some advance the broadcasts online before airing on their cable networks. Hulu, Fancast and Spreety are among a few providers available who collect all the legal content in one place for easy viewing by the user.

What is WhiteHatt?
Since stations became required to broadcast high-definition TV signals, televisions that can pick up these signals have been in popularity. High definition televisions offer viewers clearer images, better and sharper surround sound technology and most importantly, pictures that have superior resolutions. This article discusses why high definition televisions are the way to go.
Why High Definition Televisions?
1. Superior Picture Resolution
Televisions that are able to pick up and transmit HD signals offer a much higher picture resolution than most of the televisions that use digital technology and not high def. This results in a sharper picture quality if you have a high definition television.
2. Increased Aspect Ratio
Digital televisions currently available feature an aspect ratio of 4:3, whereas the aspect ratio for high definition televisions is much higher at about 16:9. An aspect ratio is the height and width of the screen.
This means that a 4:3 ratio features a screen that is four feet in width and 3 feet in height and the same for an aspect ratio of 16:9 found on high def television. This higher aspect ration on high def televisions mean that these TVs have a much crisper and clearer image quality than digital televisions.
3. Surround Sound - Dolby A3 Digital
The Dolby A3 digital surround sound is featured on these televisions and is the standard on most high definition televisions. This means that high def televisions offer independent channels (5.1) of stereo surround sound that is of a compact disc quality which is frequently referred to as AC-3.
4. Decrease in the Motion Artifacts
Motion artifacts, a few of which are dot crawls and ghosting present on less technologically advanced televisions are reduced on HD televisions which makes high def televisions a viewing pleasure for most if not all of those with these televisions.
Additional Considerations High Definition Television Purchase
1. Input and output jacks on high def televisions should be paid attention to by potential buyers which must be compatible with other equipment to be attached to the television such as DVD players, consoles for video games, cables connections, etc.
2. High def tuner compatibility to the high HD television is crucial. Check the compatibility to the satellite or cable service used before purchase.
3. Will the buyer need an external antenna for any off air broadcasting. First check to ensure that the HD television can receive off air broadcasts. If the HD television cannot easily receive these broadcasts that are off air, the buyer may need to use his/her own antenna that is external.
HD televisions are the way to go and you should be able to find one that meets your desires and your budget easily. High definitions televisions means that you will have superior viewing capacity.
