A single person did not create the Internet that we know and use today. Below is a listing of different people who have helped contribute to and develop the Internet.

The initial idea of the Internet is credited to Leonard Kleinrock after he published his first paper entitled "Information Flow in Large Communication Nets" on May 31, 1961.

In 1962, J.C.R. Licklider became the first Director of IPTO and gave his vision of a galactic network. Also, with ideas from Licklider and Kleinrock, Robert Taylor helped to create the idea of the network that later became ARPANET.

How was Internet created

Why should we pay money to ISP

• Because it costs money to maintain the equipment.

ISPs connect...to ISPs. The internet is a vast system of interconnected networks, and in order to be on one of those networks, you need to pay a fee. Did you think that the 'internet' was just some big, free, self-maintaining ethersphere or something? Well it's not. It's cabling and routers and switches and UPSs and backup generators and central offices and names and addresses and all of those need to be maintained and run by actual people who really do want to be able to feed their families...which requires....MONEY!!!
