It’s Over! Final Broadcast Primetime Network Ratings For 2009-10 Season
The 2009-10 broadcast primetime season is in the books, and above are the final ratings averages for the season.
Fox’s win for adults 18-49 was its sixth in a row, and CBS’ win for average viewership was for the seventh time in the last eight years.
While the press and the networks round the ratings to one digit past the decimal point for reporting (and usually PR boasting) purposes, for the final chart, I decided to show three digits (which is the level of detail you’d see if I was showing viewer numbers instead.
For a variety of reason’s I’m not including my usual adjustments for non-annual events like the Winter Olympics which boosted NBC, but you can still see those in my post through week 35, which was all but 3 days of the season.
Note that the chart includes RATINGS not VIEWERSHIP as was typical in our weekly network ratings posts prior to July, 2009.
Fox finished marginally ahead of last season in all but adults 25-54 where they were marginally behind.
While CBS was effectively flat in viewership, adults 18-49 and adults 25-54, they can thank the Super Bowl. Without the Super Bowl, their losses in the adult demo groups would be in the same range as ABC’s.
Without the Winter Olympics, NBC would have done somewhat worse vs. last season than the chart indicates, and in all cases their season’s declines would have been worse than ABC’s.
No special exceptions for ABC, the numbers speak for themselves.
As with the final primetime ratings averages above, I performed the comparisons with last season using the maximum level of ratings detail I received instead of just one digit past the decimal point so the changes above may vary slightly from the ones in my post through week 35.
For a variety of reason’s I’m not including my usual adjustments for non-annual events like the Winter Olympics that boosted NBC, but you can still see those in my post through week 35, which was all but 3 days of the season.
Each rating point is a percentage of the US TV population in that demographic group and equals: 2.90 million viewers, 1.32 million adults 18-49, 0.68 million adults 18-34 and 1.24 million adults 25-54.
