Fast National ratings for Sunday, February 14, 2010.

Carried, at least in part, by the beginning of pairs figure skating coverage, NBC's Winter Olympics telecast dominated Sunday night in all key measures.

Meanwhile, although it fell significantly from its Super Bowl showcase, "Undercover Boss" still delivered big numbers for CBS in its first regular airing.

[Note that all programming was competing against the NBA All-Star Game on TNT and that it was, after all, Valentine's Day.]

Among adults 18-49, NBC averaged a 7.0 rating, far ahead of the 3.3 rating for FOX in the key demographic. CBS was third with a 2.8 rating, leaving ABC in fourth with a 1.9 rating.

Overall, NBC averaged an estimated 26.34 million viewers to go with a 14.4 rating/23 share. CBS' 6.0/10 was second, comfortably ahead of the 4.8/8 for FOX. ABC trailed with a 3.8/6.

NBC swept the primetime hours starting at 7 p.m. with the 11.7/20 for the beginning of the night's coverage from the Vancouver Winter Olympics, which also did a 5.4 demo rating.
