"This initiative is about bringing the lighter, lower barrier content to the PSP that has been so successful in other categories," Colaco said. The strategy will see over fifty studios--and counting--developing low-cost titles with "instant gratification."

"Part of that 'snackability'... is because you can deliver the content over WiFi super-fast," the Sony veteran explained. "We're making games that are just 20MB each, that's less than a minute to download - instant gratification, snackable content."

The move is no doubt spurred on by the success of Apple's iTunes App Store for its iPhone and iPod Touch, which offers thousands of games including titles from such popular franchises as Mass Effect, Doom, Worms and, of course, Peggle.

The snackable content for the PSP and upcoming download-only PSP Go will be sold in a specially-branded separate section of the PlayStation Store, hoping to reach "an audience that is changing how it consumes entertainment and applications."
