In 1955, Sam Phillips away Elvis' contract to RCA records for $35,000. According to music journalist Robert Fontenot, this was not as big a blunder as it sounds, as the music business in 1955 was a quick-cash game; no label owner, certainly not a small, regional one like Phillips, could have possibly asked for a percentage of an artists' future royalties once he was signed away. $35,000 was by far the largest amount ever paid for any artist by a major label, and no one in the business considered Rock music more than a passing fad; if anything, RCA was thought to have wildly overpaid for Elvis. Phillips proved he was indeed a shrewd businessman by investing that $35,000 in a small upstart hotel chain in Memphis. The name of that chain was the Holiday Hotel; you may know it better as the Holiday Inn. (thanks, E - Wenatchee, WA)
