Demos Year-to-Year, Thursday 2/16/12

An under-reported part of this week's ratings mess is that this same thing basically happened in this same week last year. That tends to turn me off to some of the "Nielsen glitch" theories floating around. While some of the week-to-week drops look bad, most of the year-to-year trends are not as horrible, except for shows for which they've been horrible for weeks. (See Office and Idol.)

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 2011. The 'SHOW' column compares each show with how that same show did during the same week of February sweeps 2011, no matter where it aired in 2011. 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 2011, no matter what aired there last year. If it's different, I tell you what it is in 'previous occupant.'
