Exciting news for people who were tweens in the nineties, that long ago age when “tween†wasn’t even a word yet. Beginning this fall, Nickelodeon will start airing a “The ’90s Are All That†programming block from midnight to 2 a.m., consisting of reruns of Rugrats, Kenan & Kel, Pete & Pete, The Amanda Bynes Show, All That, and Clarissa Explains It All. Finally, nostalgia gets its reckoning and everyone will have a chance to see if their old favorites hold up, or if their taste in television, if nothing else, really has matured. [Inside TV/EW]
