Sierra Entertainment

Sierra Entertainment started modestly as On-Line Systems in the late 1970s, with founders Ken and Roberta Williams programming games and managing the company from their own home. Their first game was Mystery House, the world's first graphical adventure game. In 1980 the company changed its name to Sierra On-Line and moved to Oakhurst, California, where they stayed until 1994. Today, its headquarters are now located in Bellevue, Washington. In 2001, the name was changed to Sierra Entertainment.

Sierra published King's Quest in 1984 to show off the advanced technology of the IBM PC, and the success of that game set forth one of the most popular series Sierra has ever created, and spurred them into creating numerous adventure series based on the Quest theme. In the years to come Sierra would remain on the forefront of groundbreaking computer game design, sometimes creating large blockbusters and other times failed experiments.
