Steve’s data illustrates that the 10PM hour of ABC, CBS and NBC is their lowest [except for ABC at 8pm] but the margin is not large in most cases. I do think that speaks to the advantage that Fox has maintaining their overall average, but it’s a small one.

However, for that week, if you eliminated the 10PM hour for ABC, NBC and CBS, their averages would increase a bit, but just a bit.

the numbers in the chart above are a strict average for the primetime period (7-11 Sundays, 8p-11 every other day). Since according to Nielsen (or my understanding of what they say) it’s an average of all the 15 minute time parts from 8p-11p, unless you’re FOX or CW where it’s 8pm-10pm. When the individual showtimes start and stop is not relevant since it’s the average of all 15 minute periods of the primetime window.

These are figured by averging the shows, not the times, meaning it is not accurate for shows that start at odd times, for example Fox’s sunday lineup all started at odd times

What else might be interesting is seeing what the average numbers are for ABC, CBS and NBC during *only* the hours they compete with Fox.

If we start getting the day by day data again, and one day I have a LOT of time on my hands, I’ll do that calculation.

FOX = 2 hours of primetime a night 6 days a week and 3 hours 1 day. ABC, CBS and NBC are 3 hours 6 days, and 4 hours one day. CW isn’t even on the air on Saturdays (a bad night, taken out of the average!).

Fox’s has it a bit easier than CBS, ABC and NBC from that perspective. I think I’d be interested to see what happens to this chart if you took the averages and multiplied them by # of hours broadcast.
