TELEVISION

    Mrs. M., and fellow classmates, I'm going to talk about how the television was first invented.

    Visionary inventors first received views of television's possibilities as the 19th century finished. George Cary of Boston first said sending every piece of a picture over lots of circuits in 1875, but other like W.E. Sawyer asked transmissions of images over one wire or channel by scanning picture elements in success very fast.

    Just a century later television has become a reality for everyone. Today, almost every house has at least one television. There are hundreds of broadcast, cable and satellite televisions channels sending out scores of hours of programming to viewers across the world. How did televisions develop??? How did inventors feed technology along the way??? Several key figures were responsible for television's development and growth.

    Know as the father of modern television, Vladmir Kosma Zworykin was a Russian-born American inventor whose two inventions made watching your favorite sitcom possible. Electric Corporation, Zworykin invented the inoscope in 1923 -- a tube for television transmission. The iconoscope was later replaced but laid the foundations for television cameras. The inoscope allowed pictures to be electronically broken down into hundreds of thousands of elements. By 1924, Zworykin had filled a patent application for the Kinescope or television receiver. In 1924 in Pittsburgh, Zworykin would demonstrate how television would work with his instruments. Zworykin's model for television was quite different than the television you might watch today. The screen he was working with was only one square inch-a far cry from the big screens and high definition television sets of today! In 1932, the inventor's iconoscope was able to imitate the ways that human eyes view images for television broadcast. Later, after joining the Radio Corporation of America, Zworykin also developed designs for color television, but in his life's later years, television's trivialisation of everyday life disturbed the inventor, who favored using television as a cultural enrichment and learning tool.

    During his high school years, Philo Taylor Farnsworth was busy thinking about making television work while his buddies were outside having fun. Philo later went to the Brigham Young University in Utah and pushed himself in research on television picture transmission. By 1927, at the tender age of 30, Farnsworth was the first to transmit a television image composed of 60 horizontal lines. The image transmitted was a dollar sign. Quite appropriate considering the amount of revenues that television would bring many in the decades to come! Throughout his lifetime, Farnsworth amassed some 165 patents.

    So television was born, and the invention saw many developments. American culture would change forever and keep changing with television's growth. Inventors like Peter Goldmark of CBS would revolutionize the medium with his three filter systems allowing color television. Goldmark's filter system provided a mechanical solution that needed modification. After a government-led regulatory process prior to color television's implementation, color broadcast began in 1953. Later, Goldmark would achieve fame for the first electronic video recording system -- the forerunner for the VCR in your home today. Television took off. It was showcased at the 1939 World's Fair in New York, were regular broadcasting began. NBC and CBS's programming took off in the early 1940's, and by the middle of the decade, over 20 stations flourished. Pittsburgh was the home of not only the first radio station but the first public.
