Sierra

Founded in 1979 as On-Line Systems. Renamed to Serra On-Line in 1982. Acquired by CUC in 1996 and in 1997 CUC merged with HFS Incorporated to form Cendant Corporation. In 1998 a scandal with Cendant’s finances led to a sale of it’s software division Havas SA, combining Sierra. On February 22, 1999, Sierra reorganized it’s company leading to many development groups being shut down and cancellations of game projects including Space Quest 7 and Leisure Suit Larry 8. Sierra became more of a publisher after 1999. In late 2000, a merger of multiple companies including Havas SA led to Vivendi Universal. In 2002 Sierra On-Line was renamed to Sierra Entertainment. Sierra was closed down in 2008.
