The Wayback Machine is a digital archive of the World Wide Web founded by the Internet Archive, a nonprofit based in San Francisco, California. Created in 1996 and launched to the public in 2001, it allows the user to go "back in time" to see how websites looked in the past. Its founders, Brewster Kahle and Bruce Gilliat, developed the Wayback Machine to provide "universal access to all knowledge" by preserving archived copies of defunct web pages.
Launched on May 10, 1996, the Wayback Machine had saved more than 38.2 billion web pages at the end of 2009. As of 22 November 2023[update], the Wayback Machine has archived more than 865 billion web pages.
