When asked about his future prospect of communication satellites in 1961, US Federal Communications Commission (FCC) Commissioner Tunis Craven claimed, “There is practically no chance communications space satellites will be used to provide better telephone, telegraph, television, or radio service inside the United States.” This was eventually proven false, when a communication satellite named Syncom 3 successfully transmitted communication signals from Japan to the United States three years later, during the 1964 Olympics.

Facts About Television

The first time color TV sets outsold B&W was in 1972. That was also the first year that broadcast satellite TV began, although cable had been around for years before that. Only 20% of U.S. households had two or more sets at the time, and almost all portable TVs (usually the choice for a second set) were still black and white due to the technology involved for color. By 1979 no more black and white consoles were made. About six channels were available for watching and the average screen size was 22 inches.

During the 90s the average screen size was 27 inches and the 'giant size screens' were 40 inches. The average TV screen size is about 37 inches today and expected to average 60 inches by 2015.

Later this year super HiDef will be coming at four times the 1080p of today and the TV set definition will be 16 times greater by 2015, likely with prices to match.

New 4K TV Coming

Television manufacturers are always eager to shore up their business with new technology and are gearing up to roll out sets with what's known as 4K screen resolution. These TVs, which should start to hit store shelves in the United States later this year, have about four times the resolution of 1080p screens, the current standard for high-definition sets.

Regardless of the size of its screen, a 1080p TV has about 2 million pixels arrayed across 1,920 vertical columns and 1,080 horizontal rows. Although electronics manufacturers haven't yet settled on a standard, 4K resolutions generally have at least 7 million pixels - and sometimes many more - arranged across about 4,000 columns and 2,000 rows. All those extra pixels allow 4K televisions to display images in much finer detail than HDTVs.

On bigger screen sizes at close distances, the difference between 1080p and 4K is stunning. At a close viewing range, HD video on a big screen can look pixilated, and colors and images can blur into the background. By contrast, 4K video looks super sharp and almost lifelike. At a further distance the difference tends to be less noticeable.

You might want to wait for 4K. The first 4K TVs will likely be outrageously expensive. Toshiba's 55-inch 4K television is already available in Japan for $10,000 or so. Another reason to wait is that no shows are being produced in 4K yet. In fact very few are produced in 3D so far, but ESPN is betting that many will love the 3D sports events it will be producing.

The 4K video processor should only add about $10 to the cost of a TV, but the big cost issue is the display technology. The ability to cram that many pixels into a relatively small space is on the cutting edge of display manufacturers' capabilities.

Manufacturers will only sell about 5,000 4K TVs this year worldwide and won't sell more than a million per year until 2015. 3D TV should be selling more units by then, also.

Technology History

Television was first introduced to the American public at the 1939 World's Fair. World War II delayed commercial network programming in the US until the late 1940's. A popular black-and-white model, the 1948 Admiral, had a 7 inch screen encased in a large metal box four times the screen size. It cost $2,495 ($22,642.49 at today's cost) 

One of the earliest computers, ENIAC was introduced in 1946. It weighed 30 tons, had 6000 switches, 18,000 tubes and occupied an entire room.

The Apple iPad has a  9.7 inch screen and weighs 1.3 pounds.

Live TV on the Internet

This is very cool stuff. (link below) is a site that allows people to send in live streams from their phone or other device directly to the net and you can watch. One channel had a football game that was blacked out locally that was sent directly from a guy in another area. It also has online chat, so you can share comments with others about the show being played live.

It has multiple feeds and I can see foresee family events for the holidays, where a few people in different cities show live video and add comments. What a great way to keep in touch and better than picture phone. I made need to upgrade my phone to play with this one.
