The way back Machine is a digital time capsule created by the Internet Archive. It is maintained with content from Alexa Internet. This service allows users to see archived versions of web pages across time, what the Archive calls a “three dimensional index”. Snapshots become available 6 to 12 months after they are archived. The Wayback Machine contains almost 2 petabytes of data and is growing at the rate of 20 terabytes per month. A two-third increase over the 12 terabytes/month growth rate was reported in   2003. Its growth rate eclipses the amount of text contained in the world’s largest libraries, including the Library of Congress. The data is stored on Petabox rack systems manufactured by Capricorn Technologies.

  The name Wayback is a reference to a segment from The Rocky and Bullwinkle Show in which Mr. Peabody, a bow tie-wearing dog with a professorial air, and his human “pet boy” assistant Sherman use a time machine called The “WABAC machine” to witness, participate in, and more often than not alter famous events in history.
