when did first prerec videos appear?

Also there were abridged movies on super8.

Well I've seen some examples of pre-recorded N1500/1700 but not really movies as today. I couldn't check them out, it was only mentioned.

But if anyone has found or seen some, do post about it.


(It wouldn't really contain missing eps., but this is the most likely place people know about them. Collectors go for the machinery only so very little is known about the beginnings of pre-rec tape. )

Or if I rephrase: which companies released videos on these tapes? Perhaps they have still got records on it.

Anyone?
