Who is the inventor of the internet?

Wrong! The US military made the interent through a project called DAPRA. That is why most domains link to the United States and people have to add a country extension on the URL. It was as early as the late 1950s and 1960s. Universities made it more popular during the 1970s.

The earliest computer networks appeared in the late 50s. ARPANET was designed in the late 1960's by the US government to help fight the "Cold War". This network would eventually be opened to the public in the mid 80s and would become what we know as the "Internet" today.

Founders of the Internet include
J. C. R. Licklider - who set up the first multiple site computer network (and predicted that 6 computers would be enough to do all the computing the world would ever need.)
Robert W. Taylor - director of the ARPANET
Douglas Engelbart - set up the seond node on the ARPANET and invented the computer "mouse"
Vint Cerf - developed the TCP/IP protocol that made the Internet possible
Tim Berners-Lee - created the first "www" web site that would become the backbone for the Internet
Marc Andreessen - Invented the first web browser (Netscape)
Al Gore - chaired the Senate committee that made the decision to open the ARPANET (which was being retired by the government) to public usage and allowed commercial sties and traffic on the network
The porn industry - which was the first to use the Internet for commercial sites

You are correct that the Internet did not become "common" until the early 2000s. But some of us were on the Internet back in the 90s (AOL and CompuServe) and using Bulletin Boards in the 80s and late 70s. It was not until the early 2000s that home computer became common enough that people knew about the Internet. But it has been around since the late 1960s.

As you might expect for a technology so expansive and ever-changing, it is impossible to credit the invention of the Internet to a single person. The Internet was the work of dozens of pioneering scientists, programmers and engineers who each developed new features and technologies that eventually merged to become the “information superhighway” we know today.

The history of the Internet begins with the development of electronic computers in the 1950s. Initial concepts of packet networking originated in several computer science laboratories in the United States, United Kingdom, and France.[1] The US Department of Defense awarded contracts as early as the 1960s for packet network systems, including the development of the ARPANET. The first message was sent over the ARPANET from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute (SRI).

Packet switching networks such as ARPANET, NPL network, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of communications protocols.[2] Donald Davies first designed a packet-switched network at the National Physics Laboratory in the UK, which became a testbed for UK research for almost two decades.[3][4] The ARPANET project led to the development of protocols for internetworking, in which multiple separate networks could be joined into a network of networks.

Internet has been around since the early 80s. But it didnt really become a household thing until early 90s

There is no single one inventor, ...Although Rear Admiral Grace M. Hopper, helped invent the computer. Its the chicken or the egg theory because you needed computers to have the Internet.
