E-mail. Nobody tried to invent the e-mail. It simply happened. In 1969 an American, Ray Tomlinson, was working on two projects at the same time. Firstly, he was working on a programme called SNDMSG ( send message). With that programme the people in his company were able to leave messages for each other. The second project was a file-transfer programme (CYPNET). With that programme users were able to send files between linked computers. Suddenly Tomlinson had an idea. « If I put the two programmes together, I may be able to send messages, not just files, to other computers. » The idea worked and quickly became popular.
