DOMESTIC VIDEO
The first big breakthrough that led to today's boom in domestic video came from Japan and Holland. In 1970 Sony, JVC and Matsushita of Japan agreed to adopt a uniform standard, the U-format, for industrial and semi-professional video. U-format machines went on sale two years later, and have now become the industrial standard, worldwide. They are also used for education and broadcasting. The U-format recorder uses tape which is 19 mm or 3/4 in wide and is contained in a cassette. The user does not need to thread the tape round the videodrum. All this is done automatically as the cassette is loaded in the machine.
