Who invented the Internet?
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 idea
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 create the idea of the network that later became ARPANET .
Initial creation
The Internet as we know it today first started being developed in the late 1960's in California in the United States.
In the summer of 1968 , the Network Working Group (NWG) held its first meeting, chaired by Elmer Shapiro, at the Stanford Research Institute (SRI). Other attendees included Steve Carr, Steve Crocker , Jeff Rulifson, and Ron Stoughton. In the meeting, the group discussed solving issues related to getting hosts to communicate with each other.
In December 1968 , Elmer Shapiro with SRI released a report "A Study of Computer Network Design Parameters." Based on this work and earlier work done by Paul Baran , Thomas Marill and others, Lawrence Roberts and Barry Wessler created the Interface Message Processor (IMP) specifications. Bolt Beranek and Newman, Inc. (BBN) was later awarded the contract to design and build the IMP subnetwork.
General public learns about Internet
The UCLA (University of California, Los Angeles) put out a press release introducing the public to the Internet on July 3, 1969 .
First network equipment
On August 29, 1969 , the first network switch and the first piece of network equipment called "IMP" (Interface Message Processor) is sent to UCLA.
On September 2, 1969 , the first data moves from the UCLA host to the switch. The picture to the right is Leonard Kleinrock next to the IMP.
The first message and network crash
On Friday October 29, 1969 at 10:30 p.m., the first Internet message was sent from computer science Professor Leonard KleinRock's laboratory at UCLA, after the second piece of network equipment was installed at SRI. The connection not only enabled the first transmission to be made, but is also considered the first Internet backbone .
The first message to be distributed was "LO", which was an attempt at "LOGIN" by Charley S. Kline to log into the SRI computer from UCLA. However, the message was unable to be completed because the SRI system crashed. Shortly after the crash, the issue was resolved, and he was able to log into the computer.
E-mail is developed
Ray Tomlinson sends the first network e-mail in 1971.  It's the first messaging system to send messages across a network to other users.
TCP is developed
Vinton Cerf and Robert Kahn design TCP during 1973 and later publish it with the help of Yogen Dalal and Carl Sunshine in December of 1974 in RFC 675. Most people consider these two people the inventors of the Internet.
First commercial network
A commercial version of ARPANET , known as Telenet , is introduced in 1974 and considered to be the first Internet Service Provider ( ISP ).
Ethernet is conceived
