Raspberry Pi sales exceed 2.5 million as it reaches its second birthday

The Raspberry Pi Foundation, with help from chipmaker Broadcom, is laying out a path toward an open source graphics driver for the tiny computer. Broadcom today “announced the release of full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack under a 3-clause BSD license,” Raspberry Pi creator Eben Upton wrote in a blog post.

Happy Birthday Raspberry Pi! The low-cost Linux microcomputer has just turned two years old. And boy how it’s grown. The Cambridge, U.K.-based creators of the $25/$35 credit-card sized computer thought they would only ever sell a few thousand units when they started their project. In the event, they sold 100,000 units of the Model B Pi on the very first day. Global sales of all Pi models have now pushed passed 2.5 million, up from 1.75 million back in October. The Pi continues to be used in all manner of creative ways — including as a learning platform for teaching kids about computers and coding, which was actually the original mission of the Pi Foundation. And also as a plaything for adults, with makers and fully-fledged startup businesses using it to power all manner of cool stuff.  Long may it continue.
