Beginning in the 1880s, many scientists and inventors were working on a system to broadcast light images including German, Russian, American, Hungarian, and Scottish. The first successful system for broadcasting and receiving was demonstrated by John Logie Baird in 1925 in London. His system was used by the BBC for scheduled broadcasts in 1929, so beginning the first regular public broadcasts. The system in use was an electro-mechanical one, relying on spinning discs to create moving images.

Filo Farnsworth demonstrated an electro-mechanical system in 1927 in America. By 1929, he had produced the first fully electronic television system. This was an important milestone in television development because the lack of moving parts allowed resolutions to improve. His system was used for RCA's commercial broadcasting to begin in 1939 after a number of legal challenges to patents.
