Tom Silverman is a genius. Or Billboard is run by total idiots.

Maybe both. One does not preclude the other.

A billboard Guest Post By Tommy Silverman from Jan 2013

2 years later this article in Billboard.  Here Billboard reports with (almost) a straight face that Silverman is now predicting a much more pessimistic 5.5 billion dollar business by 2019.  While the journalist does address the earlier $100 billion prediction you got to wonder why Billboard would devote this sort of fawning coverage to a guy that was off by 94.5 billion dollars! The only explanation is  Tommy Silverman is truly a genius.
