The Internet Archive is mostly known for archiving the web, which the San Francisco-based nonprofit has done since 1996, two years before Google was founded.

It is also called the Wayback Machine and indexes over 435 billion webpages dating back to 1996. It is the largest archive of the web. The archive also hosts:
