All these formats were pre-recorded video movies. RCA tried to create a market for pre-recorded video "records" with their CED videodiscs. And there was Laserdisc. Laserdisc made a better picture, and RCA's discs were a little cheaper. The presence of 2 formats couldn't have helped either. And of course VHS videotape was also available. And with that, you could record your own tapes, though the image quality was pretty poor. Though one could buy porn tapes...

CED was better, but it suffered from skipping (if there was dust on the disc or in the disc material). Both disc formats were rather big, about the size of LP records.
Then comes along DVD, and they were a hit. Maybe it being digital (and full standard def quality) and physically smaller made the difference?
