Historical Background & Growth
The concept of television began with early experiments in converting visual images into electrical signals. Inventors like Paul Nipkow (Nipkow disk), John Logie Baird, and Philo Farnsworth played crucial roles in the 1920s. Mechanical televisions soon gave way to electronic systems utilizing the cathode ray tube (CRT), providing better picture quality and paving the way for mass adoption.
By the 1950s, color television was introduced, making broadcasts more engaging and lifelike. The following decades saw significant expansion in television’s reach, with satellites enabling international broadcasts, and, in India, the Satellite Instructional Television Experiment (SITE) connecting thousands of rural villages to educational and cultural programs.
Globally, the history evolution of television reflects not only technological innovation but also social change bringing the world’s events, art, and ideas directly into homes.
