Sunday night marks the end of an era for MTV: It’s the last episode of TRL, featuring cameos by Carson Daly, Justin Timberlake, and other pop-music luminaries. I figure that even though I don’t think the show has shown a video in its entirety since sometime in mid-2005, I won’t be the only member of the Idolator community watching. So won’t you join me for a liveblog? Festivities start at 8 p.m. ET, and there’s even an America’s Next Top Model marathon preceding it so your brain can get into a properly putty-like state. [TRL]
