The CW lead percentage gainers vs. week 1 of the broadcast primetime season in both average viewership and adults 18-49 ratings. Both NBC and CBS increased their adults 18-49 ratings and average viewership vs. last season’s premiere week as well. Conventional wisdom was that NBC, after opening its wallet, would be up, but the CW and CBS’ increases are both noteworthy.

On the downside, both ABC and Fox got absolutely crushed, falling 16% and 17% respectively in the all important adults 18-49 ratings compared to premiere week last season.

Note to the TV media herd: No more badgering NBC over its poor ratings performance, time to move on to ABC (and Fox, although the Super Bowl later this year will make comparisons tricky without you doing a bit of subtraction).

Taken together, the five English broadcasters were 5.5% behind their adults 18-49 ratings compared to premiere week last season.

Note: The first week of the broadcast season was the CW’s third week of new shows this season, but it was last season as well.

Here’s the season to date average ratings after week one (same as the week 1 weekly chart!)

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
