Try a Tivo.
Bonnie Hunt Show is on a lot of NBC-owned stations like WNBC, KNBC, WRC, etc. so NBC/WCAU was probably offered it as well first but passed.
Over at 10, they have the 10! show at 11, Deal or Deal at noon, Martha at 2, Ellen at 3, and 4-6 is tied with news. The only open time on Ch.10 is at 12:30pm, but its only for half an hour. If WCAU canceled 10!, they possibly could air her at 11am, but she'd probably suffer against being at the same time as The View anyways...So it would have been a lose lose, as an hour of local programming would be canceled as well, and its better for 10 to be airing a lot of local programming. And for as noon, WCAU probably thought Deal or Deal would do better.
CW 57, My 17 and Fox 29 have their schedules set in a certain way, and CW 57's morning schedule is mainly court room blocks, and My17 is mainly trashy talk show blocks.
CBS3 has a ton of shows it got first (The Doctors, Dr.Phil, maybe even Dr.Oz), they could have even gotten Rachael Ray, but she seems doing ok on WABC and WPVI.
Another alternative for Bonnie Hunt is to get cleared on WFMZ 69, and/or WMGM 40, much like how shows get cleared on WLNY 55 in the New York market, this to supplement the big city viewing. They have newscasts and a more diverse daytime lineup, compared to stations like WPHL that are mainly running blocks of one type of programming.
If Bonnie Hunt shows strong numbers in New York, LA, and other markets, then its very likely NBC/WCAU would re-evaluate the situation.
I'd doubt she move to WTXF, as Fox would likely schedule something for all its stations to replace Mike&Juliet.
