It is interesting to note that Sam Phillips - the man credited with discovering and helping to make Elvis Presley into a star - only made $35,000 off Elvis (by selling his contract with Elvis to Atlantic Records). Phillips, however, made millions from being an early investor in the Holiday Inn corporation.
I just find it interesting that Phillips' fame comes from playing a part in a cultural phenomenon from which he made very little but his main financial success is likewise very little known or remembered. Our society will make make a bozo who appears on a reality show famous yet a man who makes millions by building a business and creating hundreds of jobs can walk down any street in anonymity. Funny world we live in.
