History
Netscape made the code of its Communicator browser suite open-source in March 1998. The Mozilla Organization was then created to develop a browser from this code. It released a browser suite named Mozilla on June 5, 2002, but later changed its focus to the standalone browser Mozilla Firefox.
In 2003, the Mozilla Organization officially launched as the 501(c)(3) non-profit Mozilla Foundation to continue projects based on the Mozilla Suite source code. In August of 2005, the foundation created a for-profit arm called Mozilla Corporation to handle Firefox marketing and distribution, and in 2008 it created another for-profit arm called Mozilla Messaging.
