2010-11 SEASON vs. 2009-2010 SEASON (Through April 10,2011, Week 29 of 35)
For the 2010-11 broadcast primetime season to date vs. last season at the same week:
- ABC is DOWN 9.2% vs. last season's adults 18-49 average.
- CBS is DOWN 8.7% vs. last season's 18-49 average. If I somewhat crudely remove the ratings effect of week 2010, CBS would be UP 0.5% vs. last season.
- CW is DOWN 3.5% vs. last season's adults 18-49 average.
- Fox is DOWN 4.7% vs. last season's adults 18-49 average. If I somewhat crudely remove the ratings effect of week 2011, Fox would be DOWN 17.4% vs. last season.
- NBC is DOWN 15.9% vs. of its adults 18-49 average compared to last season at this point. If I somewhat crudely remove the two full weeks of Winter Olympics ratings from last season (which still leaves the initial days of Olympics coverage), NBC would be DOWN 1.9% vs. last season.
- Univision is UP 9.4% vs. last season's adults 18-49 average.
By my calculation (using Nielsen data) the overall average adults 18-49 ratings season to date for the 5 English broadcast networks are down 9.5% vs. the season to date ratings average through the same week of the 2009-10 season. After crudely removing two weeks of the Winter Olympics from last year, the 5 English broadcast networks would still be down 6.3%.
That overall ratings decline is pretty close to the ~5% ratings decline typical for broadcast primetime over the long term. And no, those viewers aren't surfing the net or reading books, they're watching ad supported cable networks.
Notes: The CW replaced one hour of their schedule last season (10%) that was a scheduled repeat with an original series this season. NBC is spending a lot more this season in primetime after replacing 5 hours of The Jay Leno Show with mostly scripted dramas.
Note that the % increases and declines calculated use the average adults 18-49 viewership, NOT the adults 18-49 ratings rounded to a single digit past the decimal point.
2010-11 SEASON TO DATE RATINGS (Through week 29 of 35, March 28 - April 10, 2011)
Fox will, once again, finish first among broadcast networks in the advertiser important adults 18-49 ratings for the 2010-11 season, and CBS will finish second. CBS fans can whine all they want about the unfair advantage of the, but even without it Fox would certainly have passed CBS, the just sped up the timetable.
NBC and ABC are in a season to date adults 18-49 third place tie, but that won't last for the rest of the season. ABC will certainly pull ahead of NBC before the end of the season.
