In October 2001, with 30 billion stored webpages, the Internet Archive
launched the Wayback Machine, for users to be able to surf the archive
of the web by date. In 2004, there were 300 terabytes of data, with a
growth of 12 terabytes per month. There were 65 billion webpages (from
50 million websites) in 2006, 85 billion webpages in 2008, and 150
billion webpages in March 2010. Founded in April 1996 by Brewster
Kahle, the Internet Archive is a non-profit organization that has built
an "internet library" to offer permanent access to historical
collections in digital format for researchers, historians, scholars,
and the general public. Since then, an archive of the web has been
stored every two months or so.
