A long-time radio pal shared this item from AllAccess:

DELMARVA BROADCASTING adds an FM partner for Talk WICO-A/ SALISBURY- OCEAN CITY, MD, flipping WXMD (MAX FM)/POCOMOKE CITY, MD to Talk as WICO-FM and installing separate programming from the AM side. The WICO-FM calls move from 97.5, which changes to WKTT, but retains its Country format and CAT COUNTRY slogan.

After a 5-6a simulcast of “AMERICA IN THE MORNING,” the FM carries syndicated QUINN AND ROSE, PREMIERE’s GLENN BECK and RUSH LIMBAUGH, TALK RADIO NETWORK’s JERRY DOYLE, MICHAEL SAVAGE, and RUSTY HUMPHRIES, and then simulcasts WESTWOOD ONE’s JIM BOHANNON and PREMIERE’s “COAST TO COAST AM” with GEORGE NOORY. Weekends feature music programming.

The AM side is carrying DIAL GLOBAL’s MICHAEL SMERCONISH, TRN’s LAURA INGRAHAM, DIAL GLOBAL’s NEAL BOORTZ, syndicated DAVE RAMSEY, DIAL GLOBAL’s CLARK HOWARD and TRN’s MICHAEL SAVAGE. Weekends include “best ofs” from LIMBAUGH, HOWARD and BOORTZ along with the syndicated KIM KOMANDO, CIGAR DAVE, TAMMY BRUCE, and CAR AND DRIVER shows.

My pal estimates that four major network syndicators provide 95% of programming on 80% of all talk stations in the country. Just a guess, he says, but not far off.
