Sierra Entertainment functioned as a software label that published titles developed by independent creators. Established in 1979 by Ken and Roberta Williams, the company was responsible for producing and distributing numerous highly successful games and franchises across multiple platforms from 1980 until 2008. After 2004, Sierra discontinued its own game development activities and operated exclusively as a publishing imprint under its parent company, Vivendi Games. In 2014, the Sierra brand was revived as an indie game publisher within Activision Blizzard.

(For conciseness, the extensive catalog from 1981 through 2008 is not shown here; Sierra's collection features prominent franchises such as King's Quest, Leisure Suit Larry, Police Quest, Space Quest, Gabriel Knight, alongside collaborations with studios including Dynamix, Impressions Games, Monolith Productions, Valve Corporation, among others. The company broadened its reach across platforms like Apple II, DOS/Windows PCs, consoles including PlayStation, Xbox, GameCube, and handheld devices.)

Following 2004, Sierra transitioned from internal development to focusing on publishing third-party games under Vivendi Games. The label became known for influential series within adventure, simulation, and strategy genres. After being acquired by Activision Blizzard in 2014, Sierra was reestablished as a publisher dedicated to independent developers.
