DMOZ: DMOZ is an abbreviated name for the website directory.mozilla.org. Also known as the Open Directory Project (ODP), this website is a multilingual open-content directory of links on the World Wide Web, meaning that it can be copied and modified by users. Because of this quality, while DMOZ is officially owned by AOL, it is constructed and maintained by volunteer editors.
DMOZ was originally created in 1998 by Rich Skrenta and Bob Truel, two computer programmers at Sun Microsystems. Called Gnuhoo, DMOZ was required to change its name several times after other technology companies complained that their chosen titles were too similar to existing brand names. It was finally named the Open Directory Project when it was acquired by the Netscape Communications Corporation at the end of 1998. Shortly after, Netscape was became part of AOL and the ODP was included in the transfer.
As of April 2013, DMOZ reportedly had over 5,169,995 sites listed in more than 1,017,500 categories, with 97,584 editors creating and editing these listings. As a result, it is considered the largest human-edited directory of websites in the world. It is also one of the only remaining directories to allow free submissions, in contrast to the Yahoo! Directory and others which function as paid services.
