It's depressing that the shambling corpse of THE OFFICE is the only Thursday night show that seems to be totally in the clear for a full new season, regardless of who's even going to be on it next year.
Here are some numbers I put together for comparison. Just # of viewers, not audience share, and my reference was Wikipedia, so yadda yadda grain of salt.
2011-12 season to date
The Office, fall: avg 5.97 mil viewers
Up All Night, fall (8:00 Wed): 5.25
The Office, spring: 4.88
Whitney, fall (9:30 Thu): 4.42
Whitney, spring (8:00 Wed): 4.24
Parks & Rec, fall: 3.89
Community, fall: 3.67
Parks & Rec, spring: 3.58
30 Rock, spring: 3.52
Up All Night, spring (9:30 Thu): 3.41
Community, spring: 3.30
I threw out each show's highest and lowest scores before calculating their averages to allow for anomalies like Up All Night's first ep getting 11 million viewers because it premiered after the America's Got Talent finale.
