Sanyo VTC5000 Betacord advert from 1982
Technologically Sanyo has had good ties with Sony, supporting the Betamax video format from invention until the mid 1980s (the best selling video recorder in the UK in 1983 was the Sanyo VTC5000), and later being an early adopter of the highly successful Video8 camcorder format. More recently, though, Sanyo decided against supporting Sony’s format, the Blu-ray Disc, and instead gave its backing to Toshiba’s HD DVD. This was ultimately unsuccessful, however, as Sony’s Blu-ray triumphed.
