Fast National ratings for July 31, 2013.
 
Let's be honest: NBC won Wednesday in most measures due to "America's Got Talent" and not because of "Camp," but since "Camp" was up week-to-week and "AGT" was down, it seems acceptable to give the drama a little credit.
 
Among other Wednesday notables, CBS' "Big Brother" and FOX's "MasterChef" both had small drops.
