Most of the new broadcast television shows have premiered during the past three weeks and I thought it was time to draw a comparison among the top performers.

The number one show in terms of overall viewers was NCIS, with a total audience of 18.9 million. Unsurprisingly, NCIS‘s lead-out and spin-off, NCIS: Los Angeles, also had a strong premiere with 1.74 million viewers and placed in third. In between at second place The Jay Leno Show drew 17.7 million viewers. ABC placed two shows in fourth and fifth place (Dancing With the Stars and Grey’s Anatomy), but CBS nabbed by far the most spots in this list with six spots.

The 18-49 demo ratings tell a much different and more important story. CBS loses its top position, placing half as many shows. The top spots here are for Grey’s Anatomy, House, The Jay Leno Show, Family Guy and The Cleveland Show. That’s three out of the top five for Fox.

In terms of overall performance I don’t have enough data to draw much information. TVbytheNumbers.com does have an excellent post comparing the broadcast network performance during the first week of this Fall season to last year. The only networks that are showing positive growth in overall viewership and within the 18-49 demo are MyNetworkTV and CBS.

I did draw a comparison between the network ratings by averaging out results within three time slots. While not indicating that a particular network is leading, these results do show that the highest ratings were drawn around 9:00 p.m.

This result probably has a lot to do with DVR viewership. These ratings are Live+SD (same day) meaning that time-shifted viewing before 3:00 a.m. the same “night” is included. Furthermore, it has also been reported that during this Fall season DVR viewing increased from two hours to four or five per night and given that shows in the 9:00 p.m. time slot have normally been the most popular for DVR use, these heightened ratings at 9:00 p.m. make sense.

The downside is that shows at 10:00 p.m. suffer, competing not only with shows in their own time slot but also with time-shifted programming from 8 or 9:00 p.m. There might be an exception to this trends and it’s The Jay Leno Show‘s whose timely content may stave the DVR push from earlier time periods and attract audiences for live viewing. The Jay Leno Show has lowered DVR viewing within its time slot from 70% to 46%. A higher proportion of live viewing may also mean that the show’s audience is opting away from watching other timeshifted programming, but that could only be proven by measuring overall timeshifted viewing at 10:00 p.m.
