Who invented the internet? By now, everyone knows it wasn't Al Gore (who never actually claimed that he did). But most experts do agree that the ARPANET, a project conceived by the U.S. Department of Defense in the late '60s to link computers at research institutions across the country, gave rise to the modern-day internet as we know it. Through the '70s, ARPANET saw the first tests of file transfer protocols, listservs, and even email. Eventually, it was a proving ground for TCP/IP, networking technology that most people still use daily while they're browsing the Web or communicating with friends online.
