This document provides a brief history of the development of the Internet. It describes how ARPANET was developed in the 1960s as a network to enable communication between computers and allow data transfer to continue even if parts of the network failed. In the 1970s, TCP/IP was created as the fundamental communication protocol of the Internet, and in 1989 Tim Berners-Lee invented the World Wide Web at CERN, creating HTML and the first web browser and server. The document then discusses the evolution of the Internet from the primarily commercial Web 1.0 to the more user-focused Web 2.0, and how relationships between people and companies have changed with the rise of social media and more two-way communication online.
