Looks like The Voice is going the way of certain other reality shows with a White Male Winner curse after early seasons of diversity:
Voice's first 5 winners included 0 white guys (with only one even in 2nd). This will probably be the 4th consecutive one.
American Idol's first 6 winners included 1 white guy. 7 of the last 8 have been white guys, and the exception was due to Idol stacking the deck with sucky guys.
Big Brother's first 6 winners were half white guys. 9 of their last 11 have been.
