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.
Personal digital assistant
The first PDA, the Organizer, was released in 1984 by Psion, followed by Psion's Series 3, in 1991. The latter began to resemble the more familiar PDA style, including a full keyboard. The term "PDA" was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton. In 1994, IBM introduced the first PDA with full telephone functionality, the IBM Simon, which can also be considered the first smartphone. Then in 1996, Nokia introduced a PDA with telephone functionality, the 9000 Communicator, which became the world's best-selling PDA. Another early entrant in this market was Palm, with a line of PDA products which began in March 1996.
