TV Broadcasting started in USA in 1939. After war work was pushing ahead to develop a colour tv system. The USA started the first regular colour service in 1951. Regular colour broadcasts started in UK in 1967. After war the development of satellites for long distance transmission took place.

Video recorders are also another invation. Until the early 60s all television programmes were live or made on film. In the 1950s both Ampex in USA and UK were keen to develop video recorder. The first video recorder was demonstrated by Ampex in 1956 and the machine became a broadcast standard. Philips launched the first domestic video recorder in 1971. Japan took over the market with the Beta format, launched in 1974 and later the VHS format, launched in 1976. Video discs followed in the early 80s.
