Initially developed by [[Palm, Inc.]] (which was acquired by [[Hewlett-Packard]]), HP made the platform [[Open-source software|open source]], at which point it became ''Open webOS.''

The [[operating system]] was later sold to [[LG Electronics]], and was made primarily a [[List of smart TV platforms and middleware software|smart TV operating system]] for [[LG televisions]] as a successor to [[NetCast]]. 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 [[Palm Pre|Pre]], [[Palm Pixi|Pixi]], and [[HP Veer|Veer]] [[smartphones]], [[HP TouchPad|TouchPad]] [[tablet computer|tablet]], LG's smart TVs since 2014, LG's smart refrigerators and smart projectors since 2017.

====Developer Mode====

Developer mode allows for developer access of the device, and is also used for digital forensic investigations. It can be accessed by typing ''webos20090606'' on the device’s keyboard, or on some devices typing ''upupdowndownleftrightleftrightbastart'' (a reference to the [[Konami code]]) on the cards view. Once in developer mode, data on the system partition can be accessed freely, even if the device was locked.<ref>{{cite journal |last1=Casey |first1=Eoghan |last2=Cheval |first2=Adrien |last3=Lee |first3=Jong Yeon |last4=Oxley |first4=David |last5=Song |first5=Yong Jun |title=Forensic acquisition and analysis of palm webOS on mobile devices |journal=Digital Investigation |date=July 1, 2011 |volume=8 |issue=1 |pages=37–47 |doi=10.1016/j.diin.2011.04.003 |url=https://www.sciencedirect.com/science/article/abs/pii/S1742287611000405 |language=en |issn=1742-2876}}</ref><ref>{{cite web | url=https://www.engadget.com/2009/06/10/the-secret-to-palm-pre-dev-mode-lies-in-the-konami-code/ | title=The secret to Palm Pre dev mode lies in the Konami code | date=June 10, 2009 }}</ref>
