Trio is a network that is available on a limited number of local cable companies but mainly via satellite. I like it for its music specials, some of which are quite excellent, and for rerunning old episodes of Rowan & Martin's Laugh-In. (Alas, they seem to have a limited number of episodes which they recycle.) The network is about to add reruns of Late Night with David Letterman, the show ol' Dave did for NBC. The actual airings commence in January but as a preview, they'll be running a 53-hour marathon over Thanksgiving weekend. If I'm reading the press release correctly, the total package they've acquired from NBC consists of 80 episodes, so they'll probably be rerun over and over and over, the way the same Laugh-Ins get rerun over and over and over. Which is not to say it won't be great to see those old Letterman shows again for the first few times.
