18 Jun In 2000, an open source application and open standards -based protocol called Jabber was launched
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, [citation needed] which they called "On-Line Messages" (or OLM for short), and later "FlashMail." [citation needed] (Quantum Link later became America Online [citation needed] and made AOL Instant Messenger (AIM), discussed later). While the Quantum Link service 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.
