As noted by Fortune, Apple's App Store passed the 250,000 applications accepted milestone on Friday, just two years and 49 days after it launched.

As of Saturday morning, by this count (which doesn't include apps available only overseas), there were 251,007 applications from 50,304 publishers available for download for the iPhone, iPad or iPod touch. AppShopper.com, which keeps a similar list, has the total at 253,777 apps, including 24,334 for the iPad.

According to the report, books own 17% of the App Store market, with games at 14% and entertainment at 11%. Data from Royal Pingdom is showing that about 70% of App Store apps are paid, in contrast to the Android Marketplace where 64% of the apps are free.
