Although I watch a fair bit of US TV shows, I've never really understood how the TV companies seem to come to some of their decisions on canning/renewing shows beyond the possibility they flip a coin in some cases.

The system takes no account of things like PVRs and the like. When shows like Dollhouse and The Sarah Connor Chronicles are scheduled for a Friday night when the target demographic audience they're after is more likely to be out doing things at the start of their weekend, is it a surprise that these shows get lower live viewing figures and high PVR figures?

Can somebody explain it to the simpletons among us how these studios think? Surely in these times of serious advertising cutbacks, it makes more sense to retain a known and trusted show they can be more sure of the ratings on than can it in favour of some unknown that bombs?

Sorry - rant over!
