webOS, also known as LG webOS, is a Linux kernel-based multitasking operating system for smart devices, such as smart TVs, that has also been used as a mobile operating system. It was initially developed by Palm, Inc. for its Smartphones. After Palm was acquired by Hewlett-Packard, HP made the platform open source, at which point it became Open webOS.
LG Electronics later acquired the operating system from HP, and subsequent releases targeted LG televisions, succeeding NetCast as LG's primary smart TV platform. In January 2014, Qualcomm announced that it had acquired technology patents from HP, which included all the webOS and Palm patents; LG licenses them to use in their devices.
Various versions of webOS have been featured on several devices since launching in 2009, including Pre, Pixi, and Veer smartphones, TouchPad tablet, LG's smart TVs since 2014, LG's smart refrigerators and smart projectors since 2017.
