Fox launched its four-show comedy block Tuesday night, with mixed results.

The network moved Raising Hope to 8 p.m., returned I Hate My Teenage Daughter  to 8:30 p.m., put the popular New Girl as the anchor at 9 p.m., and then had the season premiere of Christian Slater’s Breaking In at 9:30 p.m. This is the first time in at least a decade that Fox has attempted a two-hour sitcom block.

Raising Hope (4.8 million viewers, 2.1) managed to remain steady despite opening the night. Teenage Daughter (3.8 million, 1.6) was down 20 percent from its last telecast (which had a stronger X Factor lead-in, but still… ). New Girl (6 million, 3.0) was admirably steady and ranked first in the adult demo for the night. Breaking In (3.6 million, 1.7) was down sharply from its American Idol-fueled premiere and the average of Raising Hope in the slot.

Still, with CBS and ABC airing plenty of repeats, Fox ranked No. 1. Also Tuesday: Cougar Town (4.4 million, 1.5) was down 6 percent and The River (4.2 million, 1.5) was unchanged. NBC’s Biggest Loser (5.7 million, 1.9) was down 5 percent to a season low.
