Unified messaging dating

Facebook Chat is a form of instant messaging, and Twitter can be thought of as a Web 2.0 instant messaging system.

Though the term dates from the 1990s, instant messaging predates the Internet, first appearing on multi-user operating systems like Compatible Time-Sharing System (CTSS) and Multiplexed Information and Computing Service (Multics) in the mid-1960s.

The Zephyr Notification Service (still in use at some institutions) was invented at MIT's Project Athena in the 1980s to allow service providers to locate and send messages to users.

Parallel to instant messaging were early online chat facilities, the earliest of which was Talkomatic (1973) on the PLATO system, which allowed 5 people to chat simultaneously on a 512x512 plasma display (5 lines of text 1 status line per person).

AOL later acquired Mirabilis, the authors of ICQ; a few years later ICQ (then owned by AOL) was awarded two patents for instant messaging by the U. ), each with its own proprietary protocol and client; users therefore had to run multiple client applications if they wished to use more than one of these networks.
