NBC started playing games with ER's start time, ensuring that my TiVo season pass for CSI would always get kicked to the curb by the higher priority ER, because they changed the start time from 10pm to 9:59, creating a conflict.
With the move of "Ed" to Friday nights, they're now doing the same thing with "Ed", starting it at 8:59, so that it will now conflict with "Boston Public".
This is just stupid. Time-shifting is the new reality; the networks simply have to deal with it. This happens in all businesses; sometimes, a fundamental change rolls through. The outfits that rage against the darkness die, and the ones that figure out how to adapt to the change make it through. It looks to me like NBC is in full-on "rage against the darkness" mode...
