So who’s really in charge of what’s going on these days at WBBM-Channel 2? Is it Bruno Cohen the owlish president and general manager of the CBS-owned station who took over a money-losing also-ran in 2008 and turned it into a profitable contender? The man who brought Chicago legends Bill Kurtis and Walter Jacobson back together and reunited them on the anchor desk? Or is it his bosses in New York, who unloaded a bunch of second-stringers from WCBS-TV (including Kate Sullivan, Steve Bartelstein and Megan Glaros) on their station here and forced Cohen to cancel his pet project, Monsters and Money in the Morning, after just seven months?
