Factual error: The film shows Bill Gates, Steve Ballmer, and other Microsoft executives meeting with IBM and convincing them to use their new operating system, MS-DOS, despite it having not yet materialized, to which end Bill and the others then go to Seattle Computer Products to acquire their 86-DOS system. In reality, IBM had approached Microsoft for an operating system. At the time, Microsoft was using the CP/M operating system developed by Digital Research, and thus recommended IBM to them. However, negotiations fell through, and IBM tasked Microsoft to find another OS for their use. To this end, Gates approached Seattle Computer Products, and purchased their 86-DOS system.
