Microsoft may have won the "browser wars" of the 1990s with its Internet Explorer offering, but the Mozilla Foundation continues to nip persistently at Microsoft's heels with its Firefox Web browser. The Mozilla Foundation was created in 2003 to carry on the open-source Web browser work of the mozilla.org project, which was spun off from Netscape Communications in 1998. In 2005 the Mozilla Foundation spun off the Mozilla Corporation, a for-profit, taxable subsidiary that is responsible for product development, marketing, and distribution of Mozilla products.
