E-mail

Email was invented in 1965 as a way for multiple users of a time-sharing mainframe computer to communicate. This eventually grew through the development of the SAGE system and then through LAN. Later in 1971 the ARPANET system developed it’s own e-mail protocols and address formats making it unique among the other email providers. It became more mainstream in the 90's and was started to be used for personal as well as buisness actions.
