Television Information

Philo Farnsworth attended Brigham Young University in Utah, where he researched television picture transmission. While in high school, Philo Farnsworth had already conceived of his ideas for television. In 1927, Philo Farnsworth was the first inventor to transmit a television image comprised of 60 horizontal lines. The image transmitted was a dollar sign. Farnsworth developed the dissector tube, the basis of all current electronic televisions.

He filed for his first television patent in 1927. Farnsworth went on to invent over 165 different devices including equipment for converting an optical image into an electrical signal, amplifier, cathode-ray, vacuum tubes, electrical scanners, electron multipliers and photoelectric materials.

Plasma Television

Plasma televisions have wide screens, comparable to the largest CRT sets, but they are only about 6 inches (15 cm) thick. Based on the information in a video signal, the television lights up thousands of tiny dots (called pixels) with a high-energy beam of electrons. In most systems, there are three pixel colors -- red, green and blue -- which are evenly distributed on the screen.

TV or not TV

There is a direct correlation between the amount of time a child spends watching TV and their scores on standardized achievement tests - the more TV watched, the lower the scores. By the time most Americans are 18 years old, they have spent more time in front of the TV set than they have spent in school, and far more than they have spent talking with their teachers, their friends or even their parents.
