Starting off with a “Viewer discretion” advisory, last night’s Big Brother (1.7/5) was full of milk-related challenges and the usual intrigue. It also had some changes unrelated to its content. Running from 8:30 to 9:30 PM last night, the veteran reality show was out of its regular slot due to overruns earlier in the night pushing CBS’s Sunday schedule off by around half an hour. Leaving the ratings a mess, the start of the network’s primetime line-up was pushed back about 20 minutes in the Central and East Coast time zones late night because the John Deere Classic Final golf tournament cut into the 60 Minutes encore that was supposed to start at 7 PM. As they stand, the melded fast nationals have BB as the highest rated show of the night and the most watched with 5.39 million viewers. Everything else on CBS except BB was encores on Sunday

Fox also had a lot of encores with a full night of repeats of its Animation Block on Sunday. However, helped by a Family Guy (1.5/5) repeat as the second highest rated show of the night and an American Dad (1.4/4) encore as No. 3, the network won the night among adults 18-49 while CBS was tops in total viewers with 4.910 million watching

Crossing Lines (0.5/2) was NBC’s only original on Sunday. Up slightly in viewership to 2.911 million from last week’s 2.897 million, the freshman Euro-based crime show fell 17% from last week to hit a new low last night among adults 18-49

ABC started its Sunday primetime with an America’s Funniest Homes Videos (0.9/3) encore followed by Celebrity Wife Swap (1.2/4) at 8 PM and Whodunnit? (1.1/3) at 9 PM before ending with a Castle (0.7/2) repeat. With the families of Andy Dick and Lorenzo Lamas changing places last night, Wife Swap was up a surging 33% from last week’s series low. Lead-out Whodunnit? was also up, rising 10% in the key demo from its July 7 show.
