Google announced today that it has surpassed 10 billion downloads in the Android Market, and to celebrate, they’re offering 10 cent downloads of “top premium apps”. That’s 90% off.

Google has partnered with some of its developers on the pricing. These include: Asphalt 6 HD, Color & Draw for Kids, Endomondo Sports Tracker Pro, Fieldrunners HD, Great Little War Game, Minecraft, Paper Camera, Sketchbook Mobile, Soundhound Infinity and Swiftkey X.

“Of course, none of these apps would have existed if it weren’t for the developers who created them,” said Dirk Dougherty on the Android Developers Blog. “Every day, these developers continue to push the limits on what’s possible and delight us in the process. For that, we thank them.”

“One billion is a pretty big number by any measurement,” he wrote. “However, when it’s describing the speed at which something is growing, it’s simply amazing. This past weekend, thanks to Android users around the world, Android Market exceeded 10 billion app downloads—with a growth rate of one billion app downloads per month. We can’t wait to see where this accelerating growth takes us in 2012.”
