Shortly thereafter the Apple I, Apple II, Commodore PET, and TRS-80 were released. Of
these computers the Apple II was by far the most successful.
• Seeing Apple’s success, IBM released the original IBM PC model. Soon afterwards a number of “IBM PC” clones were released, such as computers from Compaq. This continues to this day. Microsoft successfully negotiated a deal to provide the operating system of all
IBM’s and IBM compatible machines. This, coupled with later blunders by Apple, led to Microsoft’s assumption of a near monopoly in the computer market.
