On October 4, 1957 the Soviet Union launched the first man made satellite into orbit named Sputnik. Sputnik transmitted radio signals back to Earth. This unique new technology alarmed America and they though the soviets would win the cold war, so they decided to start making new inventions.
Transmission Control Protocol
America feared that the soviet union might attack their national telephone line which was their only way to long distance communicate. In 1962 a scientist named J.C.R. Licklider proposed a solution to resolve this problem. He thought to make computers that could talk to one another. This was the start of the ARPA NET.
World Wide Web

In 1965 a scientist developed a way to send information called packet switching. This method was an effective way of sending data and very difficult to disrupt. In October 1969, ARPA NET delivered its first message. The message was 'login' but it crashed the network and the receiving computer only received the first two letters.
At the end of the 1970s, a computer scientist named Vinton Cerf had begun to develop a way for all of the computers on all of the world’s mini-networks to communicate with one another. He called his invention “Transmission Control Protocol" or TCP.
In 1991 the 'World Wide Web' was invented by a computer programmer named Tim Berners-Lee. This was an internet that wasn't simply a way to send files from one place to another but was itself a “web” of information that anyone on the Internet could retrieve. Software such as google was a way for the world wide web to be accessed.
Since the world wide web was created many social media platforms have been popular for many as a way to communicate.
