Betamax was used a lot offshore for divers and ROV footage until it was replaced by digital recording.
Both Betamax and V2000 were better than VHS, but it was the fact that VHS got picked up by the TV rental companies in the UK that killed the other two. Betamax was used with the PCM-F1 digital audio system, the first compact digital audio recording system, so it had a long life in studios; it wasn’t replacedby digital, it was digital! It was the actual recording medium that the digital info was stored on in the studio, after being encoded by the PCM (Pulse Code Modulation)-F1 box, which I believe Sony created.
V2000 was better if only because the tape could be flipped like an audio cassette, also developed by Philips, as was CD, for that matter.
