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

The operating system was later sold to LG Electronics, and was made primarily a 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 Pre, Pixi, and Veer smartphones, TouchPad tablet, LG's smart TVs since 2014, LG's smart refrigerators and smart projectors since 2017.

History

=2009–2010: Launch by Palm=

Palm launched webOS, then called Palm webOS, in January 2009 as the successor to Palm OS. The first webOS device was the original Palm Pre, released by Sprint in June 2009. The Palm Pixi followed.{{Citation needed|date=December 2024}}

=2010–2013: Acquisition by HP; the launch of Open webOS=

In April 2010, HP acquired Palm. The acquisition of Palm was initiated while Mark Hurd was CEO, however he resigned shortly after the acquisition was completed. Later, webOS was described by new HP CEO Leo Apotheker as a key asset and motivation for the purchase. The $1.2 billion acquisition was finalized in June. HP indicated its intention to develop the webOS platform for use in multiple new products, including smartphones, tablets, and printers.{{cite magazine |last=Bajarin |first=Ben |title=HP Is Committed to Its 'webOS' Platform (and It Should Be) |series=TechLand |magazine=Time |publisher=Time Inc. |date=June 30, 2011 |url=https://techland.time.com/2011/06/30/hp-is-committed-to-its-webos-platform-and-it-should-be/#ixzz1QshLqoCZ |access-date= November 27, 2013 }}

In March 2011, HP announced plans for a version of webOS by the end of 2011 to run within Windows,{{cite news |last=Hollister |first=Sean |date=March 14, 2011 |title=HP TouchPad Coming June, webOS for PC Beta by Year's End |work=Engadget |publisher=AOL Inc. |url=https://www.engadget.com/2011/03/14/hp-touchpad-coming-june-webos-for-pc-beta-by-years-end |access-date=November 27, 2013 }} and to be installed on all HP desktop and notebook computers in 2012.{{cite news|title=Apotheker Seeks to Save HP's 'Lost Soul' With Software Growth|work=BusinessWeek|publisher=Bloomberg L.P.|date=March 9, 2011|url=http://www.businessweek.com/news/2011-03-09/apotheker-seeks-to-save-hp-s-lost-soul-with-software-growth.html|archive-url=https://web.archive.org/web/20110311121717/http://www.businessweek.com/news/2011-03-09/apotheker-seeks-to-save-hp-s-lost-soul-with-software-growth.html|url-status=dead|archive-date=March 11, 2011|access-date=March 9, 2011}} Neither ever materialized, although work had begun on an x86 port around this time involving a team in Fort Collins, Colorado; work was scrapped later in the year.{{citation needed|date=November 2016}}

In August 2011, HP announced that it was interested in selling its Personal Systems Group, responsible for all of its consumer PC products, including webOS, and that webOS device development and production lines would be halted.{{cite web|title= Developing and Distributing with HP: Developer Program Details|work= palm.com|publisher= Hewlett-Packard Development Company|year=2010|url=http://developer.palm.com/index.php?option=com_content&view=article&id=1840&Itemid=34|archive-url=https://web.archive.org/web/20101201180033/http://developer.palm.com/index.php?option=com_content&view=article&id=1840&Itemid=34|archive-date= December 1, 2010}}{{cite news |title= HP Confirms Discussions with Autonomy Corporation plc Regarding Possible Business Combination; Makes Other Announcements |work= Press release |date= August 18, 2011 |url= http://www.businesswire.com/news/home/20110818006301/en/HP-Confirms-Discussions-Autonomy-Corporation-plc-Business |access-date= August 18, 2011}}{{cite web|title=HP kills webOS, spins off PC business to focus on software|work= AppleInsider|date=August 11, 2011 |url= http://www.appleinsider.com/articles/11/08/18/hp_to_spin_off_pc_business_to_focus_on_enterprise_software.html|access-date=August 18, 2011}} It remained unclear whether HP would consider licensing webOS software to other manufacturers.

The HP Pre 3 was launched in select areas of Europe, and US-based units were available only through unofficial channels (both AT&T and Verizon canceled their orders just prior to delivery after Apotheker's (HP's CEO at the time) announcement.{{cite news|last=Fried|first=Ina|title=HP: webOS Still Coming to PCs and Printers, Pre3 Launching in "Limited" Markets|work=AllThingsD|publisher=Dow Jones & Company|date=August 22, 2011|url=http://allthingsd.com/20110822/hp-webos-still-coming-to-pcs-and-printers-pre3-launching-in-limited-markets/ |access-date=August 24, 2011}} Notably, these US Pre 3 units, having been released through unofficial channels, lacked both warranties and carried no support obligation from HP; as a result parts are nearly impossible to come by. HP announced that it would continue to issue updates for the HP Veer and HP TouchPad, but these updates have failed to materialize for the former, and the latter saw a final, unofficial release called "webOS CE" that contained only open-sourced components of webOS meant for what remained of the developer community rather than a conventional, user-centric update to the operating system. The last HP webOS version, 3.0.5, was released on January 12, 2012.{{Cite web |url=https://www.theverge.com/2012/1/12/2702658/hp-touchpad-updated-to-webos-3-0-5 |title=HP TouchPad updated to webOS 3.0.5 |last=Ziegler |first=Chris |date=January 12, 2012 |website=The Verge |access-date=August 7, 2017 }}

In December 2011, after abandoning the TouchPad and the proposed sale of the HP Personal Systems Group, HP announced it would release webOS source code in the near future under an open-source license.{{cite press release|title= HP to Contribute webOS to Open Source|url= http://www.hp.com/hpinfo/newsroom/press/2011/111209xa.html|work= HP.com |publisher= Hewlett-Packard | date= December 9, 2011|access-date= December 10, 2011}} In August 2012, code specific to the existing devices was released as webOS Community Edition (CE), with support for the existing HP hardware.{{cite web | url= https://arstechnica.com/information-technology/2012/08/hp-releases-more-open-webos-code-including-system-manager-and-core-apps/ | title= HP releases more Open webOS code, including System Manager and core apps | website= arstechnica.com | first= Ryan | last= Paul | date=August 3, 2012}} Open webOS includes open source libraries designed to target a wider range of hardware.

==Growth and decline of HP App Catalog==

The HP App Catalog was an app store for apps for the mobile devices running webOS.

On June 6, 2009, webOS launched on the Palm Pre with 18 available apps. The number of apps grew to 30 by June 17, 2009,{{cite web|url=http://www.medialets.com/blog/2009/06/18/palm-pre-prepared-for-the-spotlight|title=Palm Pre Prepared For The Spotlight?|last=Barletta|first=Bryan|date=June 18, 2009|publisher=Medialets, Inc.|access-date=March 4, 2012|archive-date=November 10, 2017|archive-url=https://web.archive.org/web/20171110224906/http://www.medialets.com/blog/2009/06/18/palm-pre-prepared-for-the-spotlight|url-status=dead}} with 1 million cumulative downloads by June 27, 2009;{{cite web|url=http://www.medialets.com/blog/2009/06/24/palm-pre-app-catalog-reaches-1-million-downloads|title=Palm Pre App Catalog Reaches 1 Million Downloads|author=Barletta, Bryan|date=June 24, 2009|publisher=Medialets, Inc.|access-date=March 4, 2012|archive-date=November 10, 2017|archive-url=https://web.archive.org/web/20171110172050/http://www.medialets.com/blog/2009/06/24/palm-pre-app-catalog-reaches-1-million-downloads|url-status=dead}} 30 official and 31 unofficial apps by July 13, 2009;{{cite web|url=http://www.precentral.net/palm-pre-homebrew-31-apps-official-app-catalog-30|title=Palm Pre Homebrew: 31 Apps.

Subsequently, the number of available apps decreased because many apps were withdrawn from the App Catalog by their owners. Examples include the apps for The New York Times and Pandora Radio. After a Catalog splash screen on November 11, 2014, announcing its deprecation, the HP App Catalog servers were permanently shut down on March 15, 2015. The number of functional apps remaining at that time is unknown but was probably much lower due to the imminent abandonment of the project.{{Cite news |url=https://www.theverge.com/2012/6/5/3062611/palm-webos-hp-inside-story-pre-postmortem |title=Pre to Postmortem: the Inside Story of the Death of Palm and webOS |last=Ziegler |first=Chris |date=June 5, 2012 |work=The Verge |access-date=November 10, 2018 }}

==Multitasking interface==

Navigation uses multi-touch gestures on the touchscreen. The interface uses "cards" to manage multitasking and represent apps. The user switches between running apps with a flick from left and right on the screen. Apps are closed by flicking a "card" up—and "off"—the screen. The app "cards" can be rearranged for organization. webOS 2.0 introduced 'stacks', where related cards could be "stacked" together.

==Synergy==

Palm referred to integration of information from many sources as "Synergy." Users can sign into multiple email accounts from different providers and integrate all of these sources into a single list. Similar capabilities pull together calendars and also instant messages and SMS text messages from multiple sources.{{cite press release |title=Palm Unveils All-new webOS |url=http://investor.palm.com/releasedetail.cfm?ReleaseID=358392 |publisher=Palm, Inc. |date=January 8, 2009 |access-date=May 27, 2009 |archive-date=August 1, 2011 |archive-url=https://web.archive.org/web/20110801213404/http://investor.palm.com/releasedetail.cfm?ReleaseID=358392|url-status=dead }}

==Over-the-air updates==

The OS can be updated without docking to a PC, instead receiving OS updates over the carrier connection.

==Notifications==

The notification area is located on the bottom portion of the screen on phones, and on the top status bar area on tablets.

On phones, when a notification comes in, it slides in from the bottom of the screen. Due to the resizable nature of the Mojo and Enyo application frameworks, the app usually resizes itself to allow unhindered use while the notification is displayed. After the notification slides away, it usually remains as an icon. The user can then tap on the icons to expand them. Notifications can then be dismissed (sliding off the screen), acted upon (tapping), or left alone.

==Sync==

By default, data sync uses a cloud-based approach rather than using a desktop sync client. The first version of webOS shipped with the ability to sync with Apple's iTunes software by masquerading as an Apple device, but this feature was disabled by subsequent iTunes software updates.

==Third-party applications==

On HP webOS, officially vetted third-party apps are accessible to be installed on the device from the HP App Catalog.{{cite web|url=http://www.palm.com/us/products/software/mobile-applications.html|title=HP webOS official website|publisher=Palm, Inc.|access-date=June 14, 2013|archive-date=May 26, 2011|archive-url=https://web.archive.org/web/20110526011335/http://www.palm.com/us/products/software/mobile-applications.html|url-status=dead}}

Programs used to distribute homebrew webOS apps include webOS Quick Install (Java-based sideloader for desktop computers) and Preware (a homebrew webOS app catalog, which must be sideloaded). If software problems do occur after installing homebrew programs, "webOS Doctor" (provided by HP) can restore a phone back to factory settings and remove changes made by homebrew apps and patches.{{cite web|url=http://ws.hpwebos.com/webosdoctor/sorry.htm|title=HP webOS Doctor|publisher=HPWebOS.com|access-date=January 6, 2014|archive-date=April 22, 2015|archive-url=https://web.archive.org/web/20150422020231/http://ws.hpwebos.com/webosdoctor/sorry.htm|url-status=dead}}

==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.{{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 |issn=1742-2876}}{{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 }}

==Smart TV features==

LG has redesigned the UI of webOS, maintaining the card UI as a feature called "Simple switching" between open TV apps. The other two features promoted by the company are a simple connection (using an animated Clippy-like character called Beanbird to aid the user through setup), and simple discovery.

Platform

{{Update section|date=March 2018}}

Underneath the graphical user interface, webOS has much in common with mainstream Linux distributions. Versions 1.0 to 2.1 use a patched Linux 2.6.24 kernel.

The list of open-source components used by the different releases of webOS, as well as the source code of and patches applied to each component, is available at the Palm Open Source webpage.{{cite web|url=http://www.openwebosproject.org/opensource/packages.html|title=Open Source Packages: HP webOS open source compliance|website=openwebosproject.org|access-date=October 28, 2013|archive-date=October 30, 2013|archive-url=https://web.archive.org/web/20131030012743/http://www.openwebosproject.org/opensource/packages.html|url-status=dead}} This page also serves as a reference listing of the versions of webOS that have been publicly released.

In 2011, Enyo replaced Mojo, released in June 2009, as the software development kit (SDK).{{cite web|author=Jesse Mendoza|title=HP Rolls Out webOS 3.0 Beta with Enyo On Board|date=March 30, 2010|url=http://www.webosroundup.com/2011/03/hp-rolls-out-webos-3-0-beta-with-enyo-on-board|access-date=April 3, 2011|archive-date=April 4, 2011|archive-url=https://web.archive.org/web/20110404061738/http://www.webosroundup.com/2011/03/hp-rolls-out-webos-3-0-beta-with-enyo-on-board/|url-status=dead}}
