HOW TO READ THIS: These are adults 18-49 rating comparisons between the date in the post title and the corresponding night in November sweeps of 2009. The "SHOW" column compares each show with how that same show did during the fourth week of November sweeps 2009, no matter where it aired in 2009. (If it aired somewhere else, I tell you when in the "day/time" column.) The "SLOT" column compares each timeslot's rating with the timeslot's rating on the corresponding night in 2009, no matter what aired there last year. (If it's different, I tell you what it is in "previous occupant.")
The year-ago Charlie Brown Thanksgiving was actually on the night after sweeps ended (AKA Thanksgiving Day), but I decided to include it since it's a special. ABC will also be running the special on Thanksgiving Day this year.
In case you're interested, here's the post I did on the corresponding night in 2009.
