In its fourth season and taking over Ellen DeGeneres' time slot on NBC, Tegna and Hearst-owned stations (technically, the programming hole was taken over on NBC-owned stations by "Dateline" reruns), Clarkson's talk show is pulling a more-than-respectable-by-today's-standards 1.4M viewers and the daily "Kellyoke" cover song segment (which is arguably the main reason to watch the show) is getting viral and social media buzz, so NBCU is rewarding it while in Chicago CBS-owned WBBM is pulling the one half-hour they carry of Drew Barrymore today and tomorrow (and probably Wednesday, since there'll be major races that won't be called yet) for an extended 9 a.m. newscast for election coverage:
For the record, the other station in Chicago that carries Drew, Weigel's CW affil WCIU, moved it in September from 9 p.m. coming out of CDub's prime time to midnight (both half-hours, through) and replaced the 9 p.m. slot with "King of Queens" reruns.
