Crockford purchased an Atari 8-bit computer in 1980 and wrote the game Galahad and the Holy Grail for the Atari Program Exchange (APX), which resulted in Chris Crawford hiring him at Atari, Inc. While at Atari, Crockford wrote another game, Burgers!, for APX and a number of experimental audio/visual demos that were freely distributed.
After Warner Communications sold the company, he joined National Semiconductor. In 1984 Crockford joined Lucasfilm, and later Paramount Pictures. He became known on video game oriented listservs in the early 1990s after he posted his memoir "The Expurgation of Maniac Mansion" to a videogaming bulletin board. The memoir documented his efforts to censor the computer game Maniac Mansion to Nintendo's satisfaction so that they could release it as a cartridge, and Crockford's mounting frustrations as Nintendo's demands became more obscure and confusing.
Together with Randy Farmer and Chip Morningstar, Crockford founded Electric Communities and was its CEO from 1994 to 1995. He was involved[clarification needed] in the development of the programming language E.

Software license for "Good, not Evil"
In 2002, in reference to President George Bush's war on "evildoers", Crockford started releasing his JSMin software under a customized open source MIT License, with the added the requirement that "The Software shall be used for Good, not Evil". This clause was carried over to JSMin-PHP, a variation of JSMin by Ryan Grove. This software was hosted on Google Code until December 2009 when, due to the additional clause, Google determined that the license was not compliant with the definition of free and open source software, which does not permit any restriction on how software may be used. JSMin-PHP was forced to migrate to a new hosting provider. According to the GNU project, the licence conflicts with Freedom 0 of the Free Software definition, and although "it may be unenforceable, we cannot presume that", therefore non-free.
Crockford's license has caused problems for some open source projects who mistook the license for an open source variant of the MIT license. Affected open source developers have asked Crockford to change the license, but he has continued to use it.
