Die Together PC v 4. This report goes to great lengths to follow the origins, history, and maturity of online messaging clients. For those readers with limited time or who are only interested in what's due in Leopard, you can skip to page 2 of this report. Sending text messages between computers is one of the oldest functions around. The Unix talk command was originally used to pass messages between user accounts on the same system, and later expanded to allow users to address users on other systems over a network like an instant alphanumeric pager.

Internet Relay Chat below expanded upon the idea of passing messages directly to a specific host by using a server-based protocol similar to email; chat messages are relayed through IRC servers.

Once logged into an server, an IRC client could participate in group chats on various channels supported on that server or distributed across a network of affiliated IRC servers.

In the mid 80s, a variety of online services introduced home users to networking over dial up, including the Source, CompuServe, Prodigy, GEnie, and Quantum. GE's network access rates were prohibitively expensive, which limited use of the system only to Apple's dealerships.

As their popularity grew, the cost of accessing online services dropped, albeit slowly. Quantum had been operating a more affordable dial up service for home users of the Commodore 64 called Quantum Link. Among the features of Quantum Link were OnLine Messages below , which allowed subscribed users to participate in real time chats with each other.

Sending OLMs was a premium service that charged an extra minute rate on top of Quantum Link's access fees. Apple struck a partnership with Quantum in to develop a graphical, consumer-oriented service called Apple Link, Personal Edition.

It was released in May However, Apple almost immediately lost interest in developing online services; by the end of , Quantum took it solo and renamed it America Online. The new AOL popularized instant messaging and the idea of a buddy list, which indicated the online status of other users.

Despite the name, OSCAR was not really open to interoperability, but rather a proprietary system; AOL limited all access to it from anything outside its own AOL IM clients, although third parties kept using reverse engineering to offer alternative replacements.

Unlike common email systems based on open standards, all three IM systems used their own proprietary methods for accounts, messaging, and presence indication, so users of each network couldn't directly send messages to each other or see if members on other networks were online.

AOL rebuffed Microsoft's attempts to build interoperability between the two systems, fearing that Microsoft would use its Windows monopoly to embrace, extinguish, and flatten AOL's remaining marketable product as it had done with DOS application partners with Office, Java in its partnership with Sun, and its other partnerships, as related in the article How Microsoft Got Its Office Monopoly.

In , Apple introduced the original iChat 1. Mac users could either use an existing AOL account or sign up for a free. Shortly before the release of This new functionality was based on the Session Initiation Protocol, an open standard for Voice over IP and video conferencing. The new iChat AV 2. Once you discover a user in your Buddy List, an audio or video chat is performed directly between the two clients, with no server intermediary.

It largely replaces H. Rather than being a central system of accounts managed by a single company, anyone can set up a Jabber server, just as anyone can set up their own Internet email server. Jabber servers relay messages and presence indication across the Internet just as email servers pass messages. Another similarity between Jabber and open email is that closed IM systems can build gateways to Jabber, allowing their messages and presence indication to be shared with clients on any network.

AOL, CompuServe and other proprietary systems built gateways to Internet email in the past; the result of that portability was that they lost their subscribers to more competitive Internet service providers. Those developments spooked Microsoft and Yahoo, who had just announced an interoperability gateway agreement between their proprietary systems.

In mid , Apple announced that the new 3. The new version also dropped the AOL running man logo below from iChat's icon. Released with Tiger in early , iChat AV 3. Until Microsoft and Yahoo! Both Apple and Google are working to create interoperability between Jabber and SIP, which overlap in some functionality. An explosion of open VoIP audio and video messaging would be devastating to the proprietary IM vendors, but would also crack open the world's telephone, long distance and mobile phone markets, replacing everything with Internet based traffic.

With open VoIP based on Jabber and SIP, companies with a natural telephone monopoly or a lock on mobile phone frequencies would be washed away and replaced by Internet infrastructure. That's pushing Google to seriously eye the available radio spectrum being auctioned off early next year. On page 2 of 2: Leopard's iChat AV 4.

In Mac OS X Leopard, Apple added a variety things that might not be commonly associated with instant messaging, including document sharing and screen sharing. Why relate screen sharing with online chat? Presence indication finds users online and reports their availability.

Along with the remote presence indication provided by AOL or Jabber networks, iChat has also long provided another discovery protocol: Apple's own Bonjour, formerly known as Rendezvous. While AOL and Jabber track users across the Internet, Bonjour tracks users on the local network, without requiring any servers to manage things. Bonjour uses the same automatic discovery technology as AppleTalk, which was released back in the mid 80s with the original Macintosh. Select the Messages tab 4.
