Modern, Internet-wide, GUI-based messaging clients as they are known today, began to take off in the mid-1990s with Pow Wow, ICQ, and AOL Instant Messenger.Similar functionality was offered by CU-See Me in 1992; though primarily an audio/video chat link, users could also send textual messages to each other. Meanwhile, other companies developed their own software; (Excite, MSN, Ubique, and Yahoo!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.
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).Early instant messaging programs were primarily real-time text, where characters appeared as they were typed. Modern implementations of real-time text also exist in instant messengers, such as AOL's Real-Time IM In the latter half of the 1980s and into the early 1990s, the Quantum Link online service for Commodore 64 computers offered user-to-user messages between concurrently connected customers, which they called "On-Line Messages" (or OLM for short), and later "Flash Mail." (Quantum Link later became America Online and made AOL Instant Messenger (AIM, discussed later).This includes the Unix "talk" command line program, which was popular in the 1980s and early 1990s. While the Quantum Link client software ran on a Commodore 64, using only the Commodore's PETSCII text-graphics, the screen was visually divided into sections and OLMs would appear as a yellow bar saying "Message From:" and the name of the sender along with the message across the top of whatever the user was already doing, and presented a list of options for responding.Instant messaging systems tend to facilitate connections between specified known users (often using a contact list also known as a "buddy list" or "friend list").Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (an Instant message service center retransmits messages from the sender to the communication device).
