CBS to flip-flop Three Rivers and Cold Case next Sunday

Update: I favor Julia’s theory in the comments below that this move is really about keeping Cold Case box set in primetime on a night where CBS anticipates some schedule delays due to overrun from having the national broadcast Gilmore Girls series dvdof the late afternoon NFL game on Sunday.
James Hibberd reports that CBS will be doing an experiment next Sunday moving Cold Case box set to 9pm and Three Rivers to 10pm to see if it improves either or both shows’ ratings.
Hibberd also reports that CBS is still Desperate Housewives seasons 1-5 dvd considering both ordering new scripts for Three Rivers, as well as ordering new episodes (5) and could be waiting to see the finals from Criminal Minds 1-4 dvd box setSunday before making a decision after Three Rivers hit season highs in the preliminary numbers.
Clearly CBS is attempting to learn something. Gossip Girl 1-2 dvd box set But whether it is that Cold Case’s ratings are or are not due to the Three Rivers lead-in or merely finding out whether True Blood seasons 1-2 dvd Cold Case fares better against Desperate Housewives than Three Rivers, potentially improving both, or whether CBS just wants to be able Entourage seasons 1-6 dvd to say “hey, see, we tried Three Rivers when it wasn’t against Desperate Housewives so don’t say we didn’t try…”Grey’s anatomy dvd box set (update: Desperate Housewives isn’t even on next week. ABC will be airing the “American Music Awards”).
