There've always been a million ways to slice and dice the Arbitron ratings. If you don't like what they say, just look at them another way -- by age group, by gender, by time of day, by whatever. Or wait a few weeks and, like Chicago's weather, they're sure to change. That's especially true since Arbitron's new Portable People Meters turned the whole ratings game upside down.
So after I reported last week the Arbitron figures for January showing a surprise upset in morning drive for Don and Roma Wade on Citadel Broadcasting news/talk WLS-AM (890), I fully expected that the competition would step up with its own set of numbers to dispute my point. Lo and behold, Tribune Co.-owned news/talk WGN-AM (720) didn't disappoint.
