Release of Wayback Machine

29 October 2001

The Wayback Machine is a free digital archive of the World Wide Web, made available to the public in October 2001 by the Internet Archive, the non-profit library founded in San Francisco by Brewster Kahle. The Internet Archive had been collecting copies of web pages since 1996, and the Wayback Machine lets users enter an address and see how a site looked on past dates. Its name is a reference to the time-travelling WABAC machine in the cartoon Rocky and Bullwinkle. It holds hundreds of billions of saved pages, and it has become a valuable tool for journalists, researchers and courts, as well as for finding pages that have been removed or changed. Users can also ask it to save a page they want to preserve.
