After five weeks of the 2010-11 broadcast season, the season to season ratings comparisons are getting worse for Fox. They're now down 16.6% in adults 18-49 ratings vs. last season.
Unfortunately for them the NLCS this season didn't rate nearly as highly as the ALCS last season (no Yankees!). The trend seem certain to get worse as they get hit by the bad year to year comparisons between the World Series. Last year they got 6 games with the Yankees. All they can hope for this season is as many games as possible. The Yankees are watching from home.
Fox had a big Fall in 2009, when it didn't, as usual, go into the holiday season trailing in the ratings. Baseball was one of the reasons. This season they seem to be returning to their patter of a relatively weak Fall. Lucky for them, they have the Super Bowl in February.
CBS (0.8%), CW (2.6%) and NBC's (3.6%) adults 18-49 ratings are all still ahead of last season's. NBC is spending a lot more this season after replacing 5 hours of The Jay Leno Show with mostly scripted dramas. The CW is probably spending ~ 11% more after replacing an hour of repeats with an hour of scripted drama.
ABC is 7.6% behind last season's adults 18-49 ratings, which is a slight improvement from the comparison last week.
Univision continues well ahead (13.7%) of last season's adults 18-49 ratings.
