Sony made PlayStation win by making game risk cheaper to take

After the Nintendo-Sony CD-ROM collaboration collapsed, Ken Kutaragi argued that Sony should build its own console. Sony's internal history says Norio Ohga approved the project in 1992 and Sony Computer Entertainment was announced in October 1993.

Sony's problem was software: it had no inherited game catalog. The answer was to recruit developers with a technical demo, PS Library basic programs, sample code and a promise that 3D-CG would become the next market.

The deeper mechanism was distribution. Sony says PlayStation CD-ROM orders could be filled in a maximum of six days, even in small lots, while ROM cartridges could take months to replenish after stock-outs. Low-cost discs also carried the data needed for 3D games.

The first 100,000 Japanese units sold quickly, and Sony reported one million units within half a year and ten million by the end of November 1996. WIPO later framed third-party developer support as critical to the early launch period.

Win developers by cutting their inventory risk

CD-ROMs lowered the cost of experimenting with larger 3D games.

Fast small-lot replenishment reduced the penalty for misforecasting demand.

Developer libraries and sample code made 3D work accessible to teams new to the hardware.

Sony Music's manufacturing and distribution know-how gave the console business a ready operating model.

A platform can beat an incumbent by changing the economics around the product, not only the product's specs.

PlayStation became the first console family member to pass 100 million units, and WIPO notes more than 7,300 games were released over its eleven-year lifespan. Sony's entry worked because it made the whole developer-retailer loop faster and less brittle.
