VHS versus Betamax: Winning by Inviting More Allies
Sony's Betamax reached the market first and many engineers thought it looked better. JVC's VHS won anyway, because JVC played a different game: recruit every manufacturer willing to join your side of the format war.
Facts drawn from Encyclopaedia Britannica and Sony's corporate history archive; interpretive framing is labeled as modeled analysis.
Sony released the Betamax home videocassette recorder in 1975, and JVC released the competing VHS format the following year. The two systems used incompatible cassette designs, so a household had to commit to one format or the other, unable to play tapes recorded on the rival system.
[VERIFIED] VHS's original cassette offered about two hours of recording time compared with Betamax's roughly one hour, letting a single VHS tape hold a full feature film, a difference that mattered enormously once video rental stores became the dominant way people watched movies at home.
