The development of the Internet goes back to 1958. At the time, the Advanced Research Projects Agency (ARPA) was established to research and develop new technology for the United States military.
During the 1960s, computers started to become more standard and get smaller. At the same time, the first online networks were established. These days were so important for future improvements.
The First Message
On October 29, 1969, a new era started. It was a very important day for the whole world because computers connected for the first time in history. They used the network then called `ARPANET`. This connection was established between the University of California at Los Angeles and the Stanford Research Institute.
Do you want to know what was the message? The first message was "LO", which was an attempt to write "LOGIN" by Charley S. Kline to log into the SRI computer from UCLA. But the message could not be completed because the SRI system crashed. In a short time after the crash, the problem was solved, and Kline logged into the computer. So, the first connection was performed and October 29, 1969 was recorded as one of the most significant days in history.
Development of the E-mail
Electronic mail is mostly used as email or e-mail. It is a method of sending digital messages from a person to one or more recipients. We all know what email servers do. They accept, forward, deliver, and store messages. But do we know how was e-mail developed?
In 1971, the first e-mail was developed by Ray Tomlinson. It is a rather exciting story when you listen to him about the big day. He tells us his experience as: ``The first message was sent between two machines that were literally side by side. The only physical connection they had (aside from the floor they sat on) was through the ARPANET. I sent a number of test messages to myself from one machine to the other. The test messages were entirely forgettable and I have, therefore, forgotten them. Most likely the first message was QWERTYUIOP or something similar. When I was satisfied that the program seemed to work, I sent a message to the rest of my group explaining how to send messages over the network. The first use of network email announced its own existence.
Arpanet introduced the first commercial network `Telenet` in 1974. It was established by Doctor Lawrence Roberts.
Telenet was the first Internet Service Provider (ISP). Since it was the first packet-switched network service that was available to the general public, various commercial and government interests paid monthly fees for dedicated lines connecting their computers and local networks to this backbone network.
In 1979, Telenet was acquired by GTE. Later on, it was acquired by Sprint in 1986 and renamed as SprintNet.
