        The Television: The idea of the television and image transmission was born in the 19th century.
George Carey of Boston first suggested sending every component of a picture over multiple circuits in 1875, but others like W.E Sawyer proposed transmission of images over a single wire or channel by rapidly scanning picture elements in succession.
Vladimir Zworykin is known to be the father of modern TV. In 1923, Zworykin invented the iconoscope, a tube for television transmission. The iconoscope laid the foundations for early television cameras.
By 1924, Zworykin completed his kinescope or television receiver (cathode-ray tube).
After these achievements, efforts where directed towards imitating the ways in which human eyes view images and developing designs for color television.
By 1927, Philo Farnsworth succeeded in transmitting a dollar sign image comprised of 60 horizontal lines. By this success, television, as we know it today, was born and this new invention saw many developments and enhancements done by many companies.
CBS and Goldmark revolutionized the filtering techniques to allow color television.
Color broadcasting first began in 1953 and later Goldmark released the first electronic video recording system (VCR).
Since that time, television took off and we can consider it to be a major turnover in human's lives, as each house owns at least one television.
Digital TV (HDTV) standards have also been set allowing higher resolutions and the transmission of a number of channels on the same frequency.
Internet audio and video streaming is another major achievement in
signal processing, where 20 Kbps videos are streamed across the Internet, allowing a number of exciting applications, on of which is digital Internet TV and radio multicasting.
