Fast National ratings for Wednesday, February 19, 2014.
 
Despite a reputation as the most popular of Olympic events, the start of the ladies figure skating competition from Sochi gave NBC only a small night-to-night bump on Wednesday, not that the less-than-impressive growth kept the network from dominating primetime in all measures.
 
In purely hypothetical terms, we'll see if NBC gets a bigger bump for Thursday's figure skating if early reports have either Ashley Wagner or Gracie Gold making a run for the medal podium.
 
FOX's second straight two-hour "American Idol" performance episode almost perfectly mimicked Tuesday's episode, but "Idol" was edged out by CBS' new "Criminal Minds" overall and only barely held off the procedural in the key demo.
 
On to the numbers...
 
Among adults 18-49, NBC averaged a 5.0 rating for Wednesday night, not-quite-doubling the 2.6 rating for FOX in the key demographic. CBS was third with a 1.8 key demo rating, followed by ABC's 0.8 key demo rating and the 0.3 key demo rating for The CW.
 
Overall, NBC averaged an estimated 20.11 million viewers and a 12.2 rating/19 share for Wednesday primetime, doubling up FOX's 6.0/9 and 9.88 million viewers.
