    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
