It looks like Fox is coming to its senses and cutting back American Idol's painfully bloated Wednesday results show from one hour to 30 minutes — effective immediately. The new comedy Life on a Stick will air at 9:30 pm/ET beginning later this month. Until then, reruns of That '70s Show will fill the time slot. In other Fox news, the network has announced that its new Pam Anderson comedy Stacked will premiere Wednesday, April 13 at 8:30 pm.
