The first demonstrations of television in the US were in 1928 by Philo Farnsworth. It was more than a decade before televisions were made and sold commercially. In 1939, RCA began producing a commercially viable product and this represented the first widely available television. In the UK, broadcasting began in 1929 using John Logie Baird's electro-mechanical system first demonstrated in 1925. It lasted only a few years and electronic systems replaced it during the 1930s. Although televisions were sold commercially during the 1930s in the UK, all broadcasting was stopped in 1939 at the start of World War II. UK television only started up again after 1944.
