iPhone has increased US handheld market share 14 percent to 19 percent in the past year, according to a Flurry report, at the expense of both PSP and DS.
DS revenue declined 5 percent to 70 percent from 2008 to 2009, said the study, while PSP sales were badly damaged, dropping 9 percent to 11 percent total cash share.
iPhone OS US games revenues, on the other hand, climbed to take nearly a fifth of the overall handheld market in the US.
iPhone isn’t the only Apple handheld device Sony and Nintendo have to worry about, either. The impending release of iPad is looking to focus heavily on gaming, with Flurry estimating that a giant 44 percent of all apps currently being tested for the device are games.
iPad ships in April.
Sony released its latest PSP iteration, the discless PSP go, towards the end of last year. Nintendo today announced 3DS, a glass-less 3D DS upgrade due for release in its next fiscal year.
