The necessary hardware for the network was designed by scientists under the supervision of Frank Heart and the network was ready for use in September 1969. Although it was slow to start with, the network was an immediate success. It grew quickly, and in 1972 Ray Tomlinson introduced electronic mail (e-mail) to the system. By the late 1980s, many other organisations and companies wanted to use a similar communication system and the term ’Internet’ came into use. In 1989, Tim Berners-Lee proposed the idea of a World Wide Web project (www) and a new universal language called HTML.
