Betamax vs VHS: Open or Proprietary?

It's 1975. You are a senior executive at Sony. You are about to launch the Betamax, a revolutionary home video cassette recorder. It boasts superior picture quality, a compact tape design, and the unmatched engineering pedigree of Sony. Your objective is simple: own the living room.

However, your rival JVC is developing a competing standard called VHS. It's bulkier and has slightly inferior video quality, but they have a radically different strategy. While Sony wants to keep Betamax a proprietary format to capture all hardware margins, JVC is aggressively courting other manufacturers (Panasonic, Hitachi, Sharp) to license and build VHS players.

The format war is about to begin. The decisions you make now will determine who controls the home entertainment market for the next two decades. This is a battle of ecosystem economics versus hardware superiority.

The principle: In network effect markets, open standards and widespread adoption beat proprietary technical superiority. Owning 100% of a dead format is worth less than owning 10% of the industry standard. Product decisions (like tape capacity) that ignore primary consumer use cases in favor of technical purity will doom an ecosystem before it even launches.
