Wikitravel is a Web-based project "to create a free, complete, up-to-date, and reliable worldwide travel guide." Launched in July 2003 by Evan Prodromou and Michele Ann Jenkins, the website is based upon the wiki model, using the Creative Commons Attribution ShareAlike license. In 2006 Internet Brands bought the enterprise and later introduced advertising to the content pages of the website. Wikitravel received a Webby Award for Best Travel Website in 2007. That same year Wikitravel's founders began Wikitravel Press which publishes print travelguides based on the website's content. The first print guides were released on February 1, 2008
