The 9:30PM time slot on Monday nights seems to have a revolving door. Earlier this season, Out of Practice, the comedy featuring Henry Winkler and Stockard Channing held this slot. Later, without explanation, that series was replaced with Courting Alex, the new Jenna Elfman vehicle. Most recently, The New Adventures of Old Christine, Julia Louis-Dreyfus' latest sitcom attempt, was scheduled in this time period. It appears that this network is limiting its committments to sitcoms until one becomes a ratings hit. Fans are not given an opportunity to decide. The demise of many good shows has been the result of time slot roulette.
