A sad truth in the field of TV technology is that the best technology is not always the one triumphs, when two competing technologies will compete with each other.

Although VHS format, in particular, won the war, many people argued that Betamax was actually the superior format. Aless prominent example can be seen in the first laser video disc format that was introduced around the same time as the VHS and Betamax tape formats. Laserdiscs essentially primitive DVD's, which were about the same size as an old-fashioned vinyl records. Even though DVD's preferred format for video cassettes are now the two video-cassette formats firmly defeated the laser disc format when it comes to consumer video.
