NBC has designated the hour of programming from 8 p.m. to 9 p.m. as “family hour.” For some reason, some are questioning this week’s “30 Rock” as maybe not fitting into this new philosophy:

The general content of the “30 Rock” episode, however, appears to work against NBC’s positioning of the show in its family hour, the 8 to 9 p.m. block of programming that Mr. Silverman said would consist of shows a family could watch together. The contestants on the island-based reality-show-within-a-show on “30 Rock” are described as 20 “holy hot mamas,” who are accompanied by 50 eighth-grade boys as they compete at tasks like “eating bugs to earn tampons.” They square off in “Erection Cove,” with the loser having to remove her bikini top and burn it in the fire. Mr. Metcalf said that the family-hour designation should be seen as offering “direction for program development,” not “black-and-white expectations” for the audience.
