A total of 5.74 million viewers tuned in to watch Sunday’s episode ‘The Book Job’, a drop-off of almost 2 million people from last week. It becomes the least-watched episode so far this season. The competition was fierce, as the show was up against the American Music Awards on ABC (10.06 million at 8.00pm), 60 Minutes on CBS (13.29 million) and Sunday Night Football on NBC (13.2 million).
Allen Gregory scored far worse, 3.97 million viewers tuned in this week, while the rest of us stayed away, but could hear the sounds of a sharpening axe looming in the distance. Against recent trends, Family Guy managed to recover Fox for the night, with 6.04 million viewers, toppling The Simpsons for the first time in a while. American Dad rounded out the night with 4.79 million viewers.
Fox was fourth placed overall as well as among adults 18-49.

Another new episode, “The Man in the Blue Flannel Pants” airs next Sunday night.
Too bad that was a great episode
I feel that even though the ratings where the lowest of the season fans must also take into affect not just the tough competition but the leading ratings for the other fox animation domination line up.
The best episode of the season!!! so bad it had low ratings!
It was a great episode, but I found that there is no advertising through out the week telling us what the episode is going to be about. Want ratings to go up do way more promo’s.
Its a shame it was the best show all night on fox or any network for that matter and IMHO It was the best episode all season with “Bart Stops To Smell The Roosevelt’s ” coming in a close second….
Definitely best of the season if not the best of the last 5 years.
I agree about best of the season but there have been some real good episodes through out the Scully and the jean era….
