There is a known fact that the first practical video tape recorder was invented in the USA by Ampex engineers in 1956. But it took about 15 or so years before Sony introduced a standard for the first widespread video cassette, called U-matic.
quote :
U-matic is a videocassette format first shown by Sony in prototype in October 1969, and introduced to the market in September 1971. It was among the first video formats to contain the videotape inside a cassette, as opposed to the various open-reel formats of the time.

Later, in 1975 Sony developed a home videocassette tape recording format called Betamax which was followed by VHS format of JVC. During so-called
Video tape format war VHS emerged as the winner.
quote :
VHS' properties include longer playing time, faster rewinding and fast-forwarding, and a less complex tape transport mechanism. The open standard used for VHS technology allowed mass production without licensing costs.[3] VHS would eventually come out as the winning video tape format, surpassing other home tape formats by the 1990s.

So, VHS format, developed in Japan quickly became a literally global standard for portable Video Tape Recorders prior to invention of DVD.
