Palm OS was developed by company Palm Incorporated with the aim of providing 'personal digital assistants' that could be carried in your hand or pocket and used to retrieve or save basic personal information. Although it often came with a pen stylus, its touchscreen technology moved seamlessly into smartphone and other third party mobile devices.
The Palm OS was first used in 1996 and has gone through several versions, including the more recent Garnet version (Palm OS 5) in 2002 and the Cobalt version (Palm OS 6) in 2004. The Garnet version was succeeded by Access Linux Platform in 2007. Palm Incorporated changed from the Palm OS platform to webOS platform in 2009.
