Bada (stylized as bada; Korean: 바다) is a discontinued mobile operating system developed by Samsung Electronics for devices such as mid- to high-end smartphones and tablet computers. The name is derived from "바다 (bada)", meaning "ocean" or "sea" in Korean. All phones running Bada were branded with the name Wave, unlike Samsung's Android devices which are branded as Galaxy.
To foster adoption of Bada, Samsung reportedly considered releasing the source code under an open-source license, and expanding device support to include Smart TVs. In June 2012 Samsung announced its intention to merge Bada into the Tizen project, while still using it in parallel with Google's Android OS and Microsoft's Windows Phone on its smartphones.
On 25 February 2013, Samsung announced that it would stop developing Bada, moving development to Tizen instead. Bug reporting was terminated in April 2014.
After the announcement of Bada, the Wave S8500, which would eventually turn to be the first Bada-based phone, was first shown to the public at Mobile World Congress 2010 in Barcelona in February 2010. Alongside Bada itself, some applications running on Bada were exhibited, including mobile videogames like Gameloft's Asphalt 5.
The Samsung Wave S8500, released in May that year, sold one million handsets over the first four weeks on the market.
According to Samsung, companies such as Twitter, EA, Capcom, Gameloft and Blockbuster revealed their support for the Bada platform by having arranged development partnerships with Samsung since before the launch, and shared a few insights about their vision for the future of mobile apps and how Bada would play a role in it. These were a showcase of what could be heard in a series of events held across the world during the year 2010, called Developer Days. In addition, it was made public the announcement of an incoming Bada Developer Challenge with a total prize of $2,700,000 (USD) throughout the launch event.
