So, WXXI should drop what shows for On Point or Day to Day? With limited time in a day, where would you propose these go and not alienate a loyal audience for Diane Rheem or TOTN? As Scott mentioned, these are available on HD3,
And thank goodness they are...I respect Diane a lot, but I personally just don't dig the show that much. Been working a later shift a lot as of late, and I like being able to get a "taste of the old country" (I moved here from Boston) with OnPoint on my commute from Brighton to Geneva in the mornings.
To get back to the discussion, I'm not sure it's something that can be easily quantified, but there is a definite difference when you've got two major NPR outlets in the same market that are direct competitors. I think it's great that WXXI has diversified as much as it has across 1370AM, 91.5-1, -2, and -3...plus WRUR...but it's nigh-impossible to have that same level of self-introspection when you're by yourself vs. when some cross-town competitor is kicking your butt in the ratings. :

Having that external motivation can be a powerful incentive to overcome institution inertia, and nobody who's worked for a public radio station is going to deny that there isn't a lot of inertia inherent to the biz. Case in point: while I don't think it's been a rousing success, I applaud WGBH for trying to revamp their schedule and better compete with WBUR. Similarly, I
really applaud WUMB for having the cojones to scrap their entire brand and re-do it from the ground up (to marked success, from what I hear about their last pledge week).
The downside, as has been mentioned by Scott, is there does tend to be a lot more duplication of the core NPR programs. By itself this isn't necessarily bad...especially if the shows are on at different times...but often it is done without care. Not to throw the stones too hard here, but let's not forget that both
Morning Edition and
All Things Considered are on WXXI-AM, WXXI-FM HD2, and on WRUR. That's not duplication? (mind you, I know some of the reasons why that arrangement is the way it is, and I'm not saying it could easily be done any other way...I'm just oversimplifying to demonstrate a point)
To put this in perspective...why doesn't WXXI air Democracy Now? I assume it's the same reason why WSKG refused (and continues to refuse) to do so: the show's "journalism" is pretty advocate instead of objective. And there's a host of technical reasons not to air it. And it can be a real turn-off for some more centric NPR listeners. Hell, I personally can't stand the show. But it gets good ratings and our listeners LOVE it. And there's been a substantial group clamoring for it. So if WEOS ever had a Rochester outlet, you bet your ass we'd air it up there. And Free Speech Radio News, and a host of other, smaller, more "fringe" shows that appeal to that audience.
