When was the first television broadcast?

Television developed gradually through the work of many inventors, but a key milestone came in January 1926, when Scottish engineer John Logie Baird publicly demonstrated a working mechanical television system in London, transmitting moving images of a human face. Around the same time, inventors such as Philo Farnsworth in the United States were developing fully electronic television, which would ultimately prove superior to mechanical designs. Regular public television broadcasting began in the 1930s, with the BBC launching a service in 1936. Television spread rapidly after the Second World War, becoming a central feature of homes and reshaping news, entertainment, and culture. What began as flickering, low-resolution grey images has evolved into today high-definition and streaming screens.
