AIM (AOL Instant Messenger) was publicly released in May 1997 as a standalone software application. While this marks the debut of the specific product known as AIM, its underlying technology evolved from an earlier messaging system.
The Public Debut of AIM Software
In May 1997, AOL Instant Messenger was made available to the public as a standalone download for Microsoft Windows. This release, though unceremonious, represented the official launch of the popular instant messaging software, allowing users outside of the main AOL service to communicate in real-time.
The Origins of AIM's Messaging Technology
The development of AIM was not an isolated event but rather an outgrowth of earlier "online messages" technology. This foundational messaging platform was originally written in the PL/1 programming language by Dave Brown, operating on a Stratus computer. This precursor system laid the groundwork for the robust instant messaging capabilities that AIM would later offer, connecting millions of users globally.
Key Milestones in AIM's Evolution
Understanding the "invention" of AIM involves recognizing both its foundational technology and its public release as a distinct product.
| Event | Date | Description |
|---|---|---|
| Precursor Technology | Undated | The original "online messages" platform, written in PL/1 by Dave Brown on a Stratus computer, served as the fundamental basis for AIM's instant messaging capabilities. This foundational work predates the standalone AIM release. |
| AIM Public Release | May 1997 | The official launch of AIM as a standalone application for Microsoft Windows. This marked the first time the software was widely available to the public, establishing its identity as a separate product for real-time communication. |
The "invention" of AIM, in terms of its public availability and distinct product identity, can therefore be directly attributed to its May 1997 release. However, its sophisticated messaging functions were built upon pioneering work in online communication that preceded this date.
