In the three days since its October 1 launch, Sony's PSP Go boosted U.S. PSP platform sales 300 percent week over week, Sony Computer Entertainment America tells Gamasutra.
"The launch of PSP Go has generated strong consumer interest in the overall PSP platform and the PlayStation Network's digital content offering," says SCEA corporate communications director Patrick Seybold.
SCEA also tells us the launch of the PSP Go has generated a "significant increase" in North American PlayStation Network revenue -- the company tells us PSP game downloads purchased from the PlayStation Store are up 200 percent in the region.
Sony said earlier this week that the PSP Go's launch boosted its portable platform 120 percent week over week in the UK -- "in line with expectations," according to the company.
The prior-edition PSP-3000 also enjoyed "a big lift" in the region thanks to the launch of Gran Turismo on UMD and Electronic Arts' FIFA 2010.
With numerous initiatives underway to entice developers to the platform, such as a reduced-price SDK and an easier approvals process, the company hopes a strong software lineup will continue to bolster its handheld.
Says Seybold, "With several blockbuster games launching digitally and on UMD in the coming weeks -- from LittleBigPlanet to Assassin's Creed Bloodlines -- we expect this momentum to continue and look forward to a strong holiday season for both the PSP Go and PSP-3000."
