DMA 3: CHICAGO
WBBM Anchor/Reporter Mike Parker To Retire
ABC’s WLS, Chicago’s most-watched news operation since the mid-1980s, on Thursday led longtime also-ran WBBM at 10 p.m. by just 7,000 homes. Among viewers age 25 to 54, closely watched by advertisers, WMAQ enjoyed a nominal advantage over WLS of one-tenth of a rating point.
