Palm, Inc. was an American company that specialized in manufacturing personal digital assistants (PDAs) and various other electronics. They were the designer of the PalmPilot, the first PDA successfully marketed worldwide, as well as the Treo 600, one of the first smartphones. Palm developed several versions of Palm OS for PDAs and smartphones. The company was also responsible for the first versions of webOS, the first multitasking operating system for smartphones, and enyo.js, a framework for HTML5 apps.

In July 2010, Palm was purchased by Hewlett-Packard (HP) and in 2011 announced a new range of webOS products. However, after poor sales, HP CEO Léo Apotheker announced in August 2011 that it would end production and support of Palm and webOS devices, marking the end of the Palm brand after 19 years.

In October 2014, HP sold the Palm trademark to a shelf corporation tied to the Chinese electronics firm TCL Corporation. Shortly afterward, TCL confirmed its plans to revive the Palm brand on future, crowdsourced smartphones.

Palm, headquartered in Sunnyvale, California, was responsible for numerous products including the Pre and Pixi as well as the Treo and Centro smartphones. Previous product lines include the Pilot 1000, Palm Pilot Pro, Palm III, Palm V, Palm VII, Zire and Tungsten. While their older devices run Palm OS Garnet, four editions of the Treo run Windows Mobile.
