SRI International
In December 2007, SRI launched a spin-off company, Siri Inc., which Apple acquired in April 2010. In October 2011, Apple announced the Siri personal assistant as an integrated feature of the Apple iPhone 4S. Siri's technology was born from SRI's work on the DARPA-funded CALO project, described by SRI as the largest artificial intelligence project ever launched. Siri was co-founded in December 2007 by Dag Kittlaus (CEO), Adam Cheyer (vice president, engineering), and Tom Gruber (CTO/vice president, design), together with Norman Winarsky (vice president of SRI Ventures). Investors included Menlo Ventures and Morgenthaler Ventures.
IPod Touch
In June 2011, iOS 5, the fifth major release of iOS software, was announced at Apple's WWDC 2011, which added notification, messaging and reminder features. Apple limited some features, most notably the voice control system Siri, to the iPhone. iOS 6, which was released on September 19, 2012 to the fourth and fifth generation iPod Touch models, contains 200 new features including Passbook, Facebook integration and Apple Maps. The fifth generation iPod Touch gained the ability to take panoramic photos, a feature shared with the iPhone 4S and iPhone 5.
