The Pixo 2.1 Interface as used in the 5th Generation Apple iPod.

Pixo was a company that developed infrastructure for wireless systems. Paul Mercer left Apple in 1994 to found Pixo. The company developed a system software toolkit in C++ which was later adopted by Apple for use in the iPod. Apple continues to use Pixo OS technology in currently shipping models^{[citation needed]}. The use of the Pixo OS in the iPod was never formally announced, although the first-generation iPod's "About iPod" display includes a mention of Pixo, and a Connectix biography of their VP of engineering Mike Neil^[1] mentions his role as "lead architect on the Pixo OS that is used in ... the Apple iPod". Apple acquired the Pixo OS shortly after shipping the iPod and removed mention of Pixo from the "About iPod" display with a firmware update to the first-generation iPod. In 2003 Sun Microsystems bought Pixo inc.

On April 9, 2007, Apple Inc. CEO Steve Jobs announced that Apple Inc. shipped its 100 millionth iPod, making the Pixo OS one of the most widely used embedded operating systems.

The Pixo application framework is written in the C++ programming language^[2].
