That was a problem with (VHS) video tape, one has to record all the tapes that you want to distribute. That makes it expensive. The pressing or moulding of discs as is done with grammophone records, with CDs and DVDs is the key to success. I can't see that in the videogram. Making one disc that plays is one, but making the next 999 999 discs is something completely different.

Getting slightly off topic, in the late 60's I worked at the EVR (Electronic Video Recording) mastering plant at Basildon.
The domestic player used a capstan drive to run a 750ft Commag spool of 8.75mm wide film past a miniature near-UV FSS CRT.
The film was monochrome and had two optical tracks allowing two progs. to be replayed.
Alternatively one track could be encoded with a subcarrier containing a colour difference signal to provide colour playback of one prog. only.
Contact printing was used from a wide master negative to produce several prints in parallel which were then slit and reeled.
The supposed copyright advantage of playback-only proved the downfall with the arrival of VHS offering both playback and recording in the domestic environment.
Cheers,
Graham
