Fast National ratings for Friday, February 14, 2014.
Was NBC's Sochi coverage sluggish on Friday night because the men's figure skating competition yielded an American-free medal podium?
Were ratings low because Friday was also Valentine's Day?
Or was Friday slow just because it was Friday?
The answer is probably "All of the above."
No matter where you put the blame, Friday night yielded NBC's lowest numbers of the 2014 Olympics, even with normally reliable figure-skating as a centerpiece. Still, NBC beat the combined totals for the other four networks in all measures.
Thanks to the Olympics and Valentine's Day, the other networks took Friday off, basically, so there aren't any other real notables, though you may be interested that an encore of the "Enlisted" premiere outdrew last week's original?
