webOS was a mobile operating system created by Palm as a successor to Palm OS, and launched in January 2009. The webOS mobile platform introduced some innovative features, such as the cards interface, that are still in use by Apple, Microsoft and Google on their mobile operating systems today. The first original webOS device was called the Palm Pre. The Palm Pixi soon followed and then versions of both phones as "plus" versions were released. webOS was a step towards serious competition for the iphone at the time as apps were growing into mainstream mobile handsets.
In 2010, HP aquired Palm specifically for webOS and in 2011 HP announced that it would use weBOS in all of it's mobile devices. HP released a new samaller $G device called the Veer and then an HP Pre 3. Following this, HP released the Touchpad, the first webOS tablet. Unfortunately the HP Touchpad never really caught on because of the lack of apps and high price, so HP was forced to change direction. They had a huge "fire sale" of their HP Touchpad units and abandoned further development. They released teh webOS source code as open source, in hopes of someone picking it up to develop it.
In early 2013, HP announced that it was licensing webOS to LG for use on it's web-enabled smart TVs and replace its older NetCast platform. Today, LG is using webOS on all of it's smart plus TVs and has expanded use to various IoT devices. In early 2015, LG even showcased a smartwatch running on webOS.
