After three weeks of the 2010-11 broadcast season, Univision has increased its adults 18-49 ratings average by 8.6% vs last season. While among English broadcasters, CW is up 3.6% in adults 18-49 vs. 2009-10. CBS is up  1.6% vs. last season, and NBC is up 0.9% vs. last season. I wouldn’t be surprised if both CBS and NBC slip below last season in the coming weeks.

On the downside, both ABC and Fox continue well below last year’s ratings pace, down 9.6% and 12.0% respectively in the all important adults 18-49 ratings compared to their averages after three weeks last season.

Broadcast network ratings calculated average: My calculation (not Nielsen’s) of the average adults 18-49 ratings season to date for all 5 English broadcast networks is 4% below the season to date ratings average through week 3 of the 2009-10 season.

CBS maintains its season lead in primetime adults 18-49 ratings for the season after two weeks averaging a 3.3 rating. NBC and Fox are tied in second place with a 2.8 adults 18-49 ratings average, while ABC is in third with a 2.7 average.

CBS is well ahead in the press release friendly season to date average viewership.

Each rating point is a percentage of the US TV population in that demographic group and equals: a 1.0 adults 18-49 rating equals 1.315 million adults 18-49

The network’s average viewership is charted in millions of viewers, just like we report all other average viewership information on the site, and adults 18-49 is charted as ratings points. Note the units (million viewers on the left, rating on the right) below the bars.
