            It was all sparked by the invention of the phonograph by Thomas Edison. The receiving and playing of professionally produced entertainment at home was now in available to the public. Throughout the long years, there has been much progress in technology and ways to transmit signals through the air waves into people's homes or through cables. After all, it's most efficient use is to entertain, inform, and educate people and to get programs into people's homes. Whether it is movies, commercials, instructional videos, music, PSA's, news, sports, TV has changed us dramatically, as it has changed itself. Whoever makes these programs has the intention of us viewing their creation, and TV makes it possible.
             Today in America our current broadcast standard is a 525 lines, and 500 dots, field per second based system called the NTSC (National Television systems Committee). It is refreshed much faster than our eye can detect, but this is necessary for the image to change on the screen. This committee was established to insure order in the development process within the industry that would be accepted by the FCC, the committee that controls what is aired on TV and the radio. This standard was created in the 40's and 50's. This resolution, 640x480, was good at the time. But today it is dwarfed by digital signals in computer monitors, where the resolution can reach an average of 1024 X 786 pixels. Each receiver sold in America to the public must be in the regulations to received the NTSC signal. This signal has proved to be a durable way of transmitting information for 50 years. But with today's technology, a new standard has been in the works, HDTV (High Definition Television), a much higher quality signal. .
             In September of 1992, the first television station in the country to send HDTV signals over the air waves was NBC's WRC-TV in Washington DC. It was then obvious that the future of TV would be HDTV.
