Internet dating messages


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).

Many applications allow file transfers, although they are usually limited in the permissible file-size.

It is usually possible to save a text conversation for later reference.

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

Similar server-side chat features are part of most dating websites, such as OKCupid or Plentyof Fish.

Initially, some of these systems were used as notification systems for services like printing, but quickly were used to facilitate communication with other users logged into the same machine.
