Dropping A.P. Bio is never a good idea. NBC has approved the Lorne Michaels-produced comedy for a third season -- but will feature it exclusively on its upcoming streaming platform, according to The Hollywood Reporter. The network just last month elected to cancel the half-hour sitcom starring Glenn Howerton and Patton Oswalt, much to the despair of its fans and creators. The show, which tells the story of a hapless high school biology teacher and his class of high-achieving misfits, performed well on digital but drew only lukewarm ratings on broadcast TV.
