Tizen (/ˈtaɪzɛn/) is a Linux-based operating system primarily developed by Samsung Electronics and supported by the Linux Foundation.
The project was originally conceived as an HTML5-based platform for mobile devices to succeed MeeGo. It was backed by other companies under the Tizen Association. Samsung merged its previous Linux-based OS effort, Bada, into Tizen and has since used it primarily on platforms such as smart TVs and wearable devices (until 2021).
Much of Tizen is open-source software, although the software development kit contains proprietary components owned by Samsung, and portions of the OS are licensed under the Flora License, a derivative of the Apache License 2.0 that grants a patent license only to "Tizen-certified platforms".
In May 2021, Google announced that Samsung would partner with the company on integrating Tizen features into Google's Android-derived Wear OS and committed to using it on future wearables, leaving Tizen to be mainly developed for Samsung Smart TVs.
