Fast National ratings for Friday, February 17, 2012.
 
CBS may finally have found its Friday 8 p.m. solution after "Undercover Boss" delivered the network's best time period ratings in some time. However, despite starting the night strong, CBS had to settle for a Friday split, as ABC's "20/20" special dedicated to the late Whitney Houston dominated the late evening among young viewers.
 
Meanwhile, with your Friday bubble favorites, "Fringe" was flat, "Nikita" was up slightly and "Grimm" took the evening off for NBC to get low ratings for the NAACP Image Awards.
 
Among among adults 18-49, ABC averaged a 1.9 rating, edging out CBS' 1.8 rating in the key demographic. FOX was far back in third with a 1.2 rating, with NBC's 0.9 rating and The CW's 0.6 rating lagging.
 
Overall, though, CBS won the night easily by averaging 10.29 million viewers and a 6.5 rating/11 share. ABC was second with a 4.6/8 and 7.13 million viewers. NBC's 2.3/4 and 3.43 million viewers edged out the 1.9/3 and 3.05 million viewers for FOX. The CW's 1.0/2 and 1.64 million viewers trailed.

8 p.m. - "Undercover Boss" delivered 10.73 million viewers and a 2.4 rating among adults 18-49 for its Friday premiere, doubling recent key demo averages for "A Gifted Man" and adding a couple million viewers to boot.
