The AS/400 was quickly adapted worldwide and became one of the world’s most popular business computing systems. By 1997, IBM has shipped about half a million units. As a press stunt, the 400,000th unit was presented to Greg LeMond, an entrepreneur and three-time winner of the Tour de France, in October 1996. The AS/400s operating system provides a wide breadth of functions and services within a single, fully integrated system. The system's software environment included a relational database and also ensured that programs from its predecessor, System/38, could be run as is on the AS/400, although older System/36 programs had to be recompiled.
