I will chime in and note that WCAU was pretty much blown up in the past five years as well. They brought in a ton of younger talent and market newcomers. The difference is that Comcast is willing to invest in the station. Obviously the biggest sign of their investment happened this week with the big move, but they're bringing in talent left and right and for the most part keeping them. Jim Rosenfield, Jacqueline London, Keith Jones, et al have been with the station for five years at this point and all look like they're becoming station cornerstones. Plus they made smart talent moves when it counted - Vai's move from sports has turned out to be very successful, whereas the Jim Donovan experiment in mornings has been disastrous.
And let's not forget Fox 29. They have their own problems, but look at the talent they have. Bob Kelly, Sue Serio, Kathy Orr, Dawn Timmeney are all homegrown, be it at Fox or outside of the station, and Lucy Noland gets significant social media exposure on my feed thanks to her animal activism.
CBS 3 just does not have that. They have Ukee. That's it. If they weren't doing the weather reports on 1060 they would be even more anonymous.
