On-Line Systems was renamed Sierra On-Line in 1982, and they moved to Oakhurst, California. The "Sierra" name was taken from the Sierra Nevada mountain range that Oakhurst was near, and its new logo had the image of a mountain reflecting that. By early 1984 "InfoWorld" estimated that Sierra was the world's 12th-largest microcomputer-software company, with $12.5 million in 1983 sales.
