Another media casualty of the coronavirus shutdown is around-the-clock traffic reports on WBBM 780-AM/WCFS 105.9-FM, the Entercom all-news station. At least for the time being, you’ll no longer hear “traffic and weather on the eights” between 8 p.m. and 5 a.m. daily. Evening and overnight traffic reporters Abby Ryan and Neil Fiorito remain on staff to do weekend and fill-in work for WBBM Newsradio. A third, John “Shaky” Siuntres, was among dozens of employees cut in Entercom Chicago’s mass layoffs last week.
