From this morning's Tom Taylor column...
Question – what happens when you pull the usual FM simulcast (WCFS/105.9) away from CBS Radio’s all-news WBBM/780? Now that we’re in baseball season, we can answer the question, since the Cubs air only on the AM signal. Losing the simulcast is enough to drop WBBM to second place, 7.4-6.8-5.4. (Though no doubt the Cubs bring some nice additional billing to CBS.) The all-news FM by itself pulled a 2.2 share in this April book. #1 is iHeart’s urban AC “V103” WVAZ (6.3-6.5-6.9). Third is Hubbard’s hot AC “Mix” WTMX (5.2-5.6-5.2). Fourth place is a tie between CBS rhythmic “B96” WBBM-FM (3.9-3.9-4.0) and iHeart’s top 40 “Kiss” WKSC (4.2-4.2-4.0). Former Cubs flagship WGN, the talker owned by Tribune, holds 3.1-3.3-3.4. It’s just behind CBS Radio’s classic hits “K-Hits” WJMK (2.9-3.6-3.5). Meanwhile, Cumulus classic hits WLS-FM drops (3.7-3.4-2.6). These are not the best of times for iHeart’s urban WGCI (3.3-3.2-3.1). Chicago’s got a country rivalry, between CBS Radio’s “US99.5” WUSN (2.8-2.6-2.7) and iHeart challenger “Big Country” WEBG (1.7-2.3-2.0). The former WILV, Hubbard’s re-branded AC WSHE-FM, repeats its fourth straight 2.2 share. No updraft for Cumulus talker WLS, the new home of Jonathon Brandmeier and Steve Dahl (1.2-1.2-1.1). The Windy City’s cume leader is CHR “Kiss” at 1,354,800.
