Early experiments in electromechanical television were conducted by [[Charles Francis Jenkins]] in the late 1920s in the United States, building on the work of British inventor [[John Logie Baird]]. Jenkins patented the first practical television set <ref>US Patent No.1,544,156 </ref> and operated the first television broadcasting station in the US, W3XK, in 1928.

Jenkins' system was not commercially successful and was abandoned. This probably occurred because the [[Great Depression]] intervened and made the medium a prohibitively expensive extravagance.

Government red tape also played a role in Jenkin's failure: the FCC would not allow him the use of two frequencies, so he was unable to broadcast the picture and sound simultaneously.

Other pioneers in the development of television include Philo Farnsworth and Vladimyr Zworykin. Zworkyin developed a series of electronic television camera tubes, all referred to as "iconoscopes." He worked for and was heavily backed by David Sarnoff and the Radio Corporation of America, and his devices are thus in the direct ancestry of commercial television as we know it today.
