Most [talk stations] are local in the morning.
I'd break it down a little further.
In the top 50 or so markets, it will have a local program at 6am, a syndicated program at 9 (or maybe a local host), an extended newscast at 11, Rush at 12 and a local PM Drive show.
In those same markets, the second talk station will have a local host in one daypart, probably mornings or afternoons. The third talk station, if it exists, will likely be all syndicated and possibly partially brokered.
In the next class of markets, 50 to 100, the second talk station will likely have no local staff, and the leading talk station will probably have one or maybe two local programs.
After market 100, the odds of there being any daily local talk are mediocre at best. Maybe a once-a-week program in the spirit of public service.
In unrated markets, there's a good chance the station does an extended newscast once a day.
I would say that 1000 talk show hosts "making a living" (so, excluding the home repair shows, mortgage shows, and other weekend programs) is a fair number.
