How a husband-and-wife team pioneered the graphic adventure game and built a gaming empire.
In short: In 1979, Ken and Roberta Williams founded a company that would define the golden age of PC gaming. From the first graphical adventure, Mystery House, to the legendary King's Quest series, they transformed how we play. Yet, their journey from a Simi Valley home to a billion-dollar acquisition remains a cautionary tale.
The story began when Ken Williams, a programmer, brought home a teletype terminal and discovered the text-based Colossal Cave Adventure. His wife, Roberta, was captivated but frustrated by the lack of visuals. Leveraging the Apple II's graphics capabilities, the duo created Mystery House in 1980. It was a mail-order sensation, selling 15,000 copies and proving that players craved a visual experience. This success launched the Hi-Res Adventure series and set the stage for the company's rapid expansion.
By 1982, the company rebranded as Sierra On-Line and moved to Oakhurst, California, taking its name from the nearby Sierra Nevada mountains. The 1980s saw a creative explosion, with the release of iconic titles like King's Quest, Space Quest, and Leisure Suit Larry. In 1989, the company went public on the NASDAQ. By 1995, Sierra was the market-share leader in PC games, boasting $83.4 million in sales and a net income of $11.9 million. Their ambitious projects, such as the million-selling Phantasmagoria, pushed the boundaries of interactive entertainment.
The company's trajectory shifted dramatically in 1996 when CUC International acquired Sierra for approximately $1.5 billion. The acquisition was intended to create a massive publishing conglomerate, but it soon soured due to an accounting scandal at CUC in 1998. The original founders, Ken and Roberta Williams, departed as the company was shuffled through various corporate hands. After operating as a division under Vivendi Games and later Activision, the brand was eventually shuttered in 2008 before being revived by Activision in 2014 and ultimately landing under Microsoft's ownership.
