The Wayback Machine is a digital archive of the World Wide Web and other information on the Internet. It was launched in 2001 by the Internet Archive, a nonprofit organization based in San Francisco, California, United States.


The Internet Archive launched the Wayback Machine in October 2001.[4][5] It was set up by Brewster Kahle and Bruce Gilliat, and is maintained with content from Alexa Internet.[6] The service enables users to see archived versions of web pages across time, which the archive calls a "three dimensional index".[6]

Since 1996, the Wayback Machine has been archiving cached pages of websites onto its large cluster of Linux nodes.[citation needed] It revisits sites on occasion (see technical details below) and archives a new version.[7] Sites can also be captured on the fly by visitors who enter the site's URL into a search box.[citation needed] The intent is to capture and archive content that otherwise would be lost whenever a site is changed or closed down.[citation needed] The overall vision of the machine's creators is to archive the entire Internet.[citation needed]

Information had been kept on digital tape for five years, with Kahle occasionally allowing researchers and scientists to tap into the clunky database.[8] When the archive reached its fifth anniversary, in 2001, it was unveiled and opened to the public in a ceremony at the University of California, Berkeley.[9]

The name Wayback Machine was chosen as a reference to the "WABAC machine" (pronounced way-back), a time-traveling device used by the characters Mr. Peabody and Sherman in The Rocky and Bullwinkle Show, an animated cartoon.[10][11] In one of the animated cartoon's component segments, Peabody's Improbable History, the characters routinely used the machine to witness, participate in, and, more often than not, alter famous events in history.
