Tizen

Tizen is an operating system based on Linux. It was made mainly by Samsung Electronics and supported by the Linux Foundation. It was first made to work on mobile devices using HTML5, building on work from MeeGo. Many companies joined to support it through the Tizen Association.

Samsung added its old Linux-based system, Bada, into Tizen. Today, Samsung uses Tizen mostly for smart TVs and wearable devices, but this changed in 2021.

Most of Tizen is open-source software, but some parts of its software development kit are special to Samsung. Some parts also use the Flora License, which is based on the Apache License 2.0.

In May 2021, Google said that Samsung would work with them to add Tizen features to Google's Android-based Wear OS. After this, Tizen was mostly used for Samsung Smart TVs.

History

The Tizen project began as a mobile version of Linux and launched by Intel in July 2007. In 2009, Intel gave the project to the Linux Foundation. It was later combined with Nokia’s Maemo to create MeeGo.

In 2011, the Linux Foundation started the Tizen project to continue MeeGo. Big companies like Samsung Electronics, Panasonic Mobile, and Vodafone joined to support it. Tizen was designed to work with web apps and aimed at devices like netbooks, smartphones, tablets, smart TVs, and in-car entertainment systems.

In 2013, Samsung planned to make Tizen phones and merged its Bada system into Tizen. The first Tizen tablet came out in Japan in 2013. In 2014, Samsung’s Gear 2 smartwatch used Tizen instead of Android. By 2018, Tizen became the most popular system for smart TVs. In 2021, Samsung agreed to work with Google to connect Tizen with Google’s Wear OS for wearables, but kept using Tizen for smart TVs. The Tizen app store closed in 2021, and Samsung moved its watches to Wear OS 3. As of August 2025, Samsung Smart TVs still use Tizen and get updates from Samsung.
