Internet Archive
Brewster studied AI at MIT with Marvin Minsky and Danny Hillis, and later joined Hillis at Thinking Machines where Brewster developed WAIS (sold to AOL). He later founded the early innovator of page rank, Alexa (sold to Amazon), and simultaneously created the Internet Archive, the non-profit archive of the version history of all web pages (and much more). More recently he founded the Open Content Alliance to begin digitizing, archiving and providing open access to the worlds texts.
