Betamax was a rival to VHS, which would allow consumers to watch film media in their own home. It didn't sell well, and was abandoned long before its rival.
Behind the scenes
- The "To Be Continued" screen was only added to the home release of Back to the Future. It was not originally included in the theatrical release, as a sequel was not originally planned.
- Only the first film was released on Betamax. VHS had supplanted Betamax by the time the sequels were released.
