Written Elated Nerds and Sitcoms Took a Reality Revenge by Bridger Cunningham

CBS Mondays performed just dandy this season, but the network demanded more. They juxtaposed The Big Bang Theory and Two and a Half Men at 8pm on Thursdays under the transparent guise of having "the two biggest sitcoms on this night." The strategy worked as they shoved their way into newly charted territory, pinching out NBC's Must-See-TV. Over on Monday, How I Met Your Mother led the evening, followed by failed clunkers Partners and Made in Jersey. Then an insulting, afterthought of an ending to durable Rules of Engagement. 2 Broke Girls delivered steady, as did Mike and Molly.
ABC built modest success on Wednesdays with Modern Family redefining standards. The Middle delivered a modest performance, and Suburgatory held, okay. Elsewhere, poindexters, dweebs and geeks couldn't crack the Greek standard of The Middle and MF. Last Man Standing made a bold move to Friday evenings with modest success, followed by what would begin a slew of failures to follow, starting with Malibu Country and odd showings of social misfit Happy Endings.
FOX Sundays delivered strong, and Tuesdays gave their mediocre best piggybacking on New Girl. The Mindy Project performed modestly, and Raising Hope continued to lose Nielsen steam. NBC made a hot mess as the 2000's popular remains had their day and faded. The Office and 30 Rock bowed out after successful runs, leaving Community and Parks and Recreation to fend for themselves with critical popularity saving their soft demos. Sophomores Up All Night and Whitney were shown the door, and not a single freshman pilot exited the series with a return invitation to NBC's formerly popular sorority house.
