The way Commodore licensed Basic is one of the great anecdotes in computing history. Bill Gates wanted to license it on a per-unit fee of $3, but to this proposal, Jack in his unique style replied “I’m already married” and proposed to purchase it for a one-time fee of $25.000. Gates agreed to these terms (perhaps because he didn’t believe Commodore would be selling many units anyhow) and to this date recalls that business decision as being one of the biggest missteps of his career, as surely pushing for the per-unit fee would have made him a millionaire much faster as Commodore was going to include Basic in every machine they would build.
