The document traces the origins and development of the internet from the late 1950s to present day. It began as a US government program called ARPANET created in response to the Soviet launch of Sputnik. This network eventually allowed computers at universities and research labs to communicate. E-mail was invented in 1972 and the first web browser in the early 1990s, leading to the commercialization and popularization of the internet for businesses and personal use. Now the internet allows users worldwide to access information, communicate, and perform various online activities through any connected computer.
