Fast National ratings for Sunday, March 11, 2012.
 
ABC got encouraging returns for "GCB," as the Texas dramedy's second week actually rose slightly among young viewers and helped the network win Sunday among young viewers. Of course, "GCB" still drew a smaller audience than "CSI: Miami," which ranked as Sunday's most watched show and led CBS to an easy overall win.
 
[Note that in the aftermath of Sunday morning's time change, most primetime early-evening numbers will likely be lower-than-usual this week, a peculiar phenomenon that occurs every year.]
