The document provides a history of the development of the Internet from the 1960s to present day. It begins with the conception of early computer networks by the US Department of Defense and military researchers. These early networks grew throughout the 1960s and 1970s, eventually connecting many universities. Standards and protocols like TCP/IP were established in the 1970s and 1980s, allowing for the Internet as we know it today. Commercial use expanded in the 1990s with technologies like the World Wide Web, and today the Internet connects billions of people and sites globally.
