Fun facts
This was the central format in a U.S. Supreme Court case that determined home videotaping of television and movies was legal, ruling against film industry corporations
This format famously "lost" the consumer market to VHS, a more open and cheaper format that debuted with longer initial storage capacity (120 versus 60 minutes)
The format was named after the shape of the lowercase Greek letter beta (β) because it resembles the course of the tape running through a playback device
