Brewster Kahle founded the non-profit Internet Archive in 1996 to build an online library of websites and other digital media. The Internet Archive collects and preserves web pages through its Wayback Machine, allowing users to access historical versions of websites. It has archived over 330 billion web pages and grows by over 15,000 copies of the Encyclopedia Britannica every month. The Internet Archive aims to preserve digital content and make it universally accessible as a record of history and culture for future generations.
