From the Wikipedia article on Hugh Hefner: "After serving in the subscription department and as a copywriter for Esquire, he left in January 1952 after being denied a $5 raise. He worked at Children's Activities, then took his biggest gamble in 1953 by lending his furniture for $600 and raising $10,000 from 45 investors - including $1,000 from his mother ("Not because she believed in the venture," he told E! in 2006. "But because she believed in her son.") - to launch Playboy."
Who would US society (or at least publishing) be different if Hefner had been given his five dollar raise and stayed on at Esquire.
