webOS

webOS is a Linux-based operating system that was originally developed by Palm for mobile devices and later adapted for other form factors. It is notable for its web-centric approach, with applications built primarily from HTML5, JavaScript, and CSS, and for introducing card-based multitasking, where open apps could be grouped and managed as floating cards. The system used a WebKit-based rendering engine and included a set of UI frameworks, such as Mojo and Enyo, to create native-like experiences from web technologies. Key features historically associated with webOS include a centralized notification and multitasking system, universal search, and an app catalog for discovering and installing software.

History and development progressed from its 2009 introduction on the Palm Pre and related devices. After Palm was acquired by HP in 2010, the platform continued as HP webOS, with a tablet line that culminated in the HP TouchPad in 2011. Following poor hardware sales, HP halted further webOS devices and eventually open-sourced the platform. In 2013–2014, LG Electronics acquired the webOS IP and began using the technology for its smart TV platform, launching webOS in televisions and expanding its ecosystem. LG also maintained an open-source edition of webOS, known as webOS Open Source Edition, for community development and broader experimentation.

Today, webOS is primarily associated with LG’s smart TVs and related devices, where it supports a TV-oriented app experience, voice features, and content discovery. The open-source edition provides a basis for developers and hobbyists to explore and contribute to the platform, while LG continues to evolve the technology for consumer electronics.
