Berkeley Systems was a San Francisco Bay Area software company cofounded in 1987 by Wes Boyd and Joan Blades. It made money early on by doing contract work for the National Institutes of Health, specifically in making modifications to the Macintosh so that it could be used by partially sighted or blind people. Several of these Access  programs were licensed by Apple Computer and added to the operating system. Perhaps the most ambitious of these technologies was a program that could read the Macintosh screen, called Outspoken, which won a technology award from the Smithsonian in 1990.
The first commercial success for Berkeley Systems was a virtual desktop product for the Macintosh called Stepping Out. Given the small size of the first Macintosh screens, this product had some use and the idea was widely copied. The much bigger success was After Dark, a modular screensaver and the first of its kind to be sold. The idea was brought to Berkeley Systems by Jack Eastman and Patrick Beard. Eastman was later put in charge of software development at Berkeley Systems.
Berkeley Systems' best-selling product, the trivia game You Don't Know Jack, was developed by Jellyvision based on their award-winning children's educational film “The Mind’s Treasure Chest”. YDKJ brought that program's model of interactive learning, engaging structure and pacing, and host character into the commercial mainstream. It also brought graphics, sound editing, and marketing to Berkeley; production of the show continued at Jellyvision's Chicago studios.
Based in the old Pac Bell building on Rose Street at Shattuck in Berkeley, California, Berkeley Systems grew to 120 employees and USD $30 million annual revenue before it was acquired by the Sierra On-Line division of CUC International in 1997 for $13.8 million. Vivendi Universal’s subsequent acquisition of Sierra, and a host of similar enterprises, enjoined diverse competing sales and marketing departments with one sole directive: sell web banner ads. As a result, Berkeley Systems became the US headquarters of French-owned Flipside.com. In early 2000, Berkeley Systems was folded into the fledgling Los Angeles-based gambling site iWin.com, per the terms of that site's acquisition by Vivendi.
The toasters were the subject of two lawsuits, the first in 1993, Berkeley Systems vs Delrina Corporation, over a module of Delrina's Opus 'N Bill screensaver in which Opus the penguin shoots down the toasters. Delrina later changed the wings of the toasters to propellers in order to avoid infringing the trademark. The second case was brought in 1994 by 1960s rock group Jefferson Airplane who claimed that the toasters were a copy of the winged toasters featured on the cover of their 1973 album Thirty Seconds Over Winterland. The case was dismissed because the cover art had not been registered as a trademark by the group prior to Berkeley Systems' release of the screensaver.
Boyd and Blades went on to found the MoveOn.org liberal political group in 1998. Blades also later co-founded MomsRising.org with Kristin Rowe-Finkbeiner in 2006.
