Wow Family Guy is a beast. Good wife pathetic repeat with a good lead in.
At its peak hour, only 22 million Americans, about 7% of the population, were watching broadcast TV on Sunday.
wow good wife didnt saw a bump even with Tony Scott death RIP
Demographics of Big Brother doesn’t fit The Good Wife! Undercover Boss in Big Brother spot! The Good Wife repeat might hold better ratings! Big Brother fits with Person of Interest and Criminal Minds! The Good Wife!
So sad for ‘The Mentalist’, it did so much better last Tuesday night at 10 PM than it did on Sunday night.
Family Guy and The Simpsons repeat really well.
