Archive is a documentary focused on the future of long-term digital storage, the history of the Internet and attempts to preserve its contents on a massive scale.
Brewster Kahle, founder of the Internet Archive, explains the purpose and function of the Internet Archive, which is housed in an old Christian Science church in San Francisco. This is the famed Wayback Machine, which lets you see a snapshot of a website as it existed since 1996. 240 billion web pages have been archived since then, and the database is updated every few months.
If that is not amazing enough, they capture the heat from the servers and reuse the energy to heat the building!
