Movie about VHS

I seemed to have read about a movie or documentary about the VHS tape and the story behind it. Has anybody else heard about this film? I can’t find the name of it at all.

is this the one? It is a movie about the guys who developed the VHS video technology. The English title is called “Dawn of a New Day: The Man Behind VHS”

Its a Japanese flick with English subtitles.

I think that’s it. Thanks!
