I think that Ghost Whisperer could compete well on Sundays at 8 with its concept and primary target audience. I know they are ditching their Sunday movie so Cold Case could always move back an hour. Though it is certainly a very tough night, especially with the NFL moving in, there's enough viewers to go around to support all of the networks. Aside from that it really depends on what it would go up against. From everything I've read so far, it looks like they plan on keeping it on Fridays. Anyway, this past Friday's numbers certainly display how important Ghost Whisperer has been to the success of CBS on Fridays.
