Starting with the fifteen dollar titles (holy jumpin' Jesus, have comic prices ever skyrocketed):
Amazing Spider-Man: Renumbered. Twice.
Avengers: Renumbered. (Heroes Reborn, Heroes Return, Heroes Get Written By Bendis)
Avengers West Coast: Canceled.
Bill & Ted's Excellent Comic Book: Apparently they could defeat Death, but not editorial. Danny Fingeroth is the balls at Connect Four, I swear. Canceled.
Captain America: Renumbered for Heroes Reborn and then at least twice since.
Conan: Canceled, moved to a different company.
Fantastic Four: Renumbered. Three times.
Guardians of the Galaxy: Canceled.
GI Joe: Canceled, moved to a different company.
Incredible Hulk: Renumbered. Twice.
Iron Man: Renumbered for Heroes Reborn and, I think, three times since.
Marvel Tales: Canceled.
Marvel Age: Canceled, relaunched recently.
New Warriors: Canceled, relaunched as an ongoing, Canceled again, followed by a couple of minis. Which I guess you could count as being Renumbered if you were really pedantic.
Punisher: Canceled, relaunched with a mini where he had magic guns and hung out with angels, relaunched as a Max book.
Sleepwalker: Canceled, almost revived on the Epic imprint, but nothing ever came of that.
Silver Surfer: Canceled, relaunched, Canceled again.
Spectacular Spider-Man: Canceled, relaunched, Canceled again.
Super-Pro: Canceled before its time.
Thor: Canceled around Heroes Reborn, relaunched, Canceled again ahead of Civil War.
Uncanny X-Men: Still Going. Holy Christ, our first Still Going, and we're on freaking U.
Web of Spider-Man: Canceled.
X-Factor: Canceled, relaunched.
X-Force: Renumbered (and renamed), Canceled.
X-Men: Still Going. Good for them.
X-Men Classics: Canceled.
Wonder Man: Canceled. Relaunched recently.
What If: Canceled (for the second time - this is the second volume, right?), revisited a couple times, but only as one-shots and minis.
What The?: Mercy killed, with at least one one-shot since.
Then-newly launched books, still fifteen bucks a year:
Cage: Canceled, with at least a mini since.
Silver Sable: Canceled.
Toxic Crusader: Canceled.
Wrestling WCW: Canceled, unsold copies since purchased by Vince McMahon and used as rolling paper.
Specially Priced Books:
Marvel Comics Presents: Canceled, but Marvel could totally use an anthology series like this now, I think. Especially if they're trying to convince me that they have fifty active superteams in America alone.
Alpha Flight: Canceled, relaunched, Canceled, and, I think, relaunched and Canceled again.
Dr Strange: Canceled, and I don't think he's had more than a mini to himself since.
Moon Knight: Canceled, recently relaunched.
She-Hulk: Canceled, relaunched, Renumbered.
The Nam: Canceled.
Deathlok: Canceled, relaunched (you remember that Marvel Tech line, or whatever it was called? I think it was Deathlok, Machine Man and, like, Warlock and none of them made it more than a dozen or so issues? Roundabouts the same time Quicksilver had a thoroughly inadvisable solo book? Wowzers), Canceled.
Excalibur: Canceled, relaunched.
Ghost Rider: Canceled, relaunched.
Punisher War Journal: Canceled, relaunched.
Punisher War Zone: Canceled.
Spider-Man Magazine: Canceled. I think it came back for a minute around the release of the first movie, but I might be wrong, there.
Wolverine: Renumbered. Maybe more than once, now that I think about it.
Warlock & the Infinity Watch: Canceled.
Groo: Canceled, moved to another company.
Conan Saga: Canceled.
Savage Sword of Conan: Canceled (I'm actually kind of shocked the market ever supported three different Conan books - which I probably shouldn't be, given the Punisher had three books out at the same time and Spider-Man had three monthlies and a magazine).
Then-New Specially Priced Books:
Terror, Inc: Canceled. Begging for a relaunch. C'mon, the guy's pretty much a zombie, and they're shitting out like three Marvel Zombie books a week now. Pretty soon, the covers will be references to prior issues of Marvel Zombies. Let Terror fight Bruce Campbell for a month and see if anyone notices.
Ghost Rider/Blaze: Canceled.
Hell's Angel: Canceled. And sued by bikers.
Darkhold: Canceled. A note on most everything south of Nomad - Marvel UK didn't do so hot, did it?
So, by my dead reckoning, that's two books (Uncanny and Merely Canny X-Men) that haven't been canceled or renumbered since May of 1992. Good golly, huh?
