San Francisco was one of the cities vying to be the official United States bid for the 2016 Summer Olympics. Like the Chicago and Los Angeles bids for the 2016 Summer Olympics, San Francisco and the entire San Francisco Bay Area in California touted a compact but regional-participatory focus for its bid, expressing an interest in developing planning partnerships with a large number of neighboring large cities. Mayor of San Francisco Gavin Newsom announced the bid on September 12, 2005. After failure to secure a venue for use as the main stadium, the bid was withdrawn on November 13, 2006.
