Sierra

Sierra is a video game company founded in 1979, as On-Line Systems, by Ken and Roberta Williams.

The company built its reputation as a company for excellent graphic adventures beginning in 1980. They only published one fully text adventure, Softporn Adventure, in 1981.

They also became well-known as a publisher, publishing games such as the original release of Ultima II: The Revenge of the Enchantress.

They continued to develop graphic adventures even after Sierra was sold to CUC International in 1996. In December 1997, CUC International merged with HFS Incorporated to become the Cendant Corporation. After the Cendant book-cooking scandal in 1998, Sierra was sold to Havas S.A, which was purchased by Vivendi (renamed Vivendi Universal in 2000 and now known as Vivendi SA) the same year. Sierra stopped producing adventure games in 1999.

Vivendi merged with Activision (forming Activision-Blizzard) in 2008, the entire Sierra staff was laid off, the Sierra building was closed, and the Sierra label was retired. Activision, who became an independent company in 2013 after they purchased Vivendi's share of the Activision Blizzard stock, brought back the Sierra label to publish games developed by independent game developers, for both original games and games developed based on the Sierra game licenses.

Sierra's earliest games were created with the Adventure Development Language, and were known as the Hi-Res Adventure series. The adventure games created with Sierra's Adventure Game Interpreter (and its predecessors) are implemented in ScummVM using the codebase from the Sarien and TrollVM projects. The adventure games created with Sierra's Creative Interpreter are implemented in ScummVM using the codebase from the FreeSCI project. All of them were done with permission obtained from the original authors of those projects.
