NBC Winter Olympics from Sochi - worst ratings ever in 18-49 demographic: http://www.deadline.com/2014/02/olympics-sochi-ratings-lowest-ever-demo-nbc/
Obviously not enough snowboard half-pipe, moguls for style points, "slopestyle", and other stuff from the X-Games.
Actually, not that I'm too mean a person, but I enjoyed that the woman who gave away her gold by doing some stupid trick over the last jump in some snowboard race in Torino has bombed out of the next two Olympics. I forget her name, Lindsey Jacobellis maybe?
[edit - Yes on LJ. I'll never root for her as a snowbaord competitor.]
