Demos Year-to-Year, Friday 2/18/11 (prelims)

As usual, NBC had the Olympics last year, so there are lots of reruns last year and lots of pluses.

HOW TO READ THIS: These are adults 18-49 rating comparisons between the date in the post title and the corresponding night in February sweeps of 2010. The "SHOW" column compares each show with how that same show did during the third week of February sweeps 2010, no matter where it aired in 2010. (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 2010, no matter what aired there last year. (If it's different, I tell you what it is in "previous occupant.")

Comparisons are (for now) between fast national (preliminary) numbers in 2011 and final national numbers in 2010.

In case you're interested, here's the post I did on the corresponding night in 2010.
