Bill Gates and Paul Allen register the trade name “Microsoft” with the Office of the Secretary of State of New Mexico. Previously, Gates and Allen had been working under an informal partnership known as “Micro-soft”, a combination of Microcomputer and Software. The partnership continued for several more years until Microsoft incorporated in July of 1981, just prior to the introduction of the IBM PC.
