REBOL was created as a messaging language for distributed Internet applications. It was designed over a 20 year period by Carl Sassenrath, the system architect responsible for the world's first multitasking multimedia operating system, the Commodore Amiga OS. The first implementation of REBOL (pronounced like "rebel yell") was released in 1997 to a small group of users running on three operating systems, and today REBOL has grown to reach more than 3,000,000 users running on more than 40 OS platforms.
