WebOS is a mobile operating system that runs on the Linux kernel. It was originally developed by Palm in 2009 as the follow-up to PalmOS. At the time it was noted for its integration of Web 2.0 technologies, open architecture, multitasking capabilities and ease of use, and featured the Synergy service that collects and synchs various contacts and calendar functions. The Palm Pre, released in June 2009 on the Sprint Nextel CDMA network, was the first device to run on webOS. Palm later followed up with the Palm Pixi. WebOS-enabled phones were subsequently introduced to the Verizon Wireless and AT&T Mobility networks in November 2009. HP acquired Palm, including the webOS system, in 2010. In 2011, HP announced that additional HP products would begin running on the webOS operating system including the HP Veer and HP Pre 3, as well as the HP TouchPad tablet. HP CEO Léo Apotheker said his company would be installing webOS within all Windows HP computers by 2012. The latest incarnation of webOS, version 2.1.0, was released in March 2011.
