Brewster Kahle founded the non-profit Internet Archive in 1996 to build an online library of the internet through archiving web pages and websites over time. The Internet Archive collects and provides access to digital cultural artifacts like web pages, software, music, texts, and videos to preserve them for future generations. It uses tools like the Wayback Machine to allow users to view archived past versions of websites and pages that have changed or disappeared from the live web. The Internet Archive aims to prevent digital history from being lost and becoming a "digital dark age" through its archiving efforts.
