From this morning's Tom Taylor column...
The “baseball split” continues, showing us what happens when you pry apart CBS Radio’s all-news WBBM and its normally-simulcast WCFS. The April book showed us that losing the FM simulcast at 105.9 cost WBBM the lead, but the AM by itself remains a strong #2, going 6.8-5.4-5.3. When the Cubs are playing, the AM runs baseball, while WCFS stays all-news – and grows, from a 2.2 last month to a 2.4. Repeating at #1 is iHeart’s urban AC “V103” WVAZ (6.5-6.9-6.8). Then comes ’BBM and Hubbard’s third-place hot AC “Mix” WTMX (5.6-5.2-4.8). Fourth is iHeart CHR “Kiss” WKSC (4.2-4.0-3.9) and fifth is CBS rhythmic “B96” WBBM-FM (3.9-4.0-3.7). Going just one peg further down, we see the remarkable spring-back of variety hits “104.3 K-Hits” WJMK, 3.6-3.5-3.5. This book, it ties with iHeart hot AC “93.9 MYfm” WLIT (3.6-3.8-3.5). No growth at Tribune’s talk WGN (3.3-3.4-3.3). Some growth at Hubbard’s re-branded AC WSHE-FM (2.2-2.2-2.5). In country, the race is CBS “US 99.5” WUSN (2.6-2.7-3.0) fending off iHeart challenger “Big” WEBG (2.3-2.0-2.4). “Big” has grown its cume to nearly 800,000, while WUSN’s steady at 1.2 million. In sports, Disney’s WMVP (1.4-1.8-2.1) edges CBS rival “Score” WSCR (2.5-2.5-2.0). Even with a new morning show, no momentum at Cumulus talker WLS (1.2-1.1-1.1). The Windy City’s cume leader is CHR “Kiss” at an average of 2,359,900.
