Human: What is the history of the internet? Assistant: 
The history of the internet dates back to the 1960s when the Advanced Research Projects Agency Network (ARPANET) was created by the United States Department of Defense as a way to link computers between universities, military sites, and other research facilities. The introduction of the Transmission Control Protocol (TCP) and Internet Protocol (IP) in the early 1980s marked the beginning of the modern internet. The World Wide Web, commonly known as the Web, was created in 1989 by Tim Berners-Lee and further developed in the early 1990s, leading to worldwide adoption. By the mid-1990s, companies such as Yahoo and Google began offering search services and web-based businesses had started to emerge. Since then, the internet has grown to become a global phenomenon, with billions of people using it for communication, entertainment, research, and commerce.
