In the Superman titles JB did something like 60 stories. The work of five years in two years. And I can add the three GENERATIONS miniseries.

Tom Palmer inked dozens of issues of AVENGERS. He remained until the last issue of Vol. I (#402), but I don't know which was the first (around #250? And I'm excluding his inks for the Silver Age issues!).

Curt Swan drawn Superman for 33 years. His first story was for SUPERMAN 3-D (1953), the last (regular) for ACTION #583.

Cary Bates, Elliot Maggin and the "Schwartz gang" wrote Superman for 15 years (1971/1986). Yes, they're not the same writer, but I consider the Schwartz period a long storyline.

Chris Claremont wrote the X-Men for 16 years (Marvel record).

Peter David wrote Hulk for 12 years.

Bendis? Oh, he can write 2000 issues of ULTIMATE SPIDER-MAN, but 2000 issues of USM are 30 stories or so.

Greg Waller: I guess I'm just less impressed with it, at least from Bendis' perspective, because he's basically just re-introducing and re-interpreting material that already exists. I think most of the praise should go to Bagley... especially in a day and age where we're told that fill-ins apparently "suck" and most artists can't produce three consecutive issues without blowing a deadline.

I understand what you're saying, but how is that really any different than some writer doing yet another Avengers vs. Ultron story, or yet another Fantastic Four vs. Doctor Doom story?  If you can accept these, why not the other?  Outside of the costumed names, in most cases the characters in ULTIMATE SPIDER-MAN don't have the same backstories or situations as their regular Marvel Universe counterparts.  Case in point, the Ultimate version of the Scorpion in issue 97.  Not Mac Gargan, not even some guy hired by Jameson to spy on Spider-Man.

Nothing is ever going to hold a candle to Stan and Jacks 102 issues on FANTASTIC FOUR.  Nothing is ever going to be as good as those 38 issues of AMAZING SPIDER-MAN by Stan and Steve.  And I don't believe Bendis or Bagley have ever said their work was in any way superior.  But, using the FF run to set yourself a goal shouldn't be considered a bad thing.

Groo got 8 issues from Pacific (I think), 120 from Marvel

Hmmm.  So the Lee/Kirby FF will soon be the 3rd longest run at Marvel with Groo being # 1 and Ultimate Spider-Man be # 2.

Seems like Stan and Jack still hold some kind of record for the longest run of comic books... that were actually good.

There was not a single bad issue of Groo, IMO

Cary Bates wrote the Flash from 1971 - 1985.

Dan Jurgens wrote Superman in various books from 1989 - 1999.

Doug Moench on Batman, despite there being gaps in-between.

He wrote Batman and Detective form 1983 - 1986. Batman = 41 issues and Detective 40 issues.

He then was involved in Batman again on a regular basis from 1990 - 2001.

Before Bendis and Bagley start crowing too loud about their supposed eclipse of Lee & Kirby on an extended run for a M***** title, someone should find out how long writer Paul S. Newman may have remained on one of the books that he wrote.

Admittedly, I'm not sure if he would end up being the champ,but it grates that the two bozos mentioned above might take the crown.

Andrew Hess: Ultimate Spider-Man has had the same writer &/or artist the whole time?

Yes. I think there have only been a small handful of inkers on the series, too.  Art Thibert being the longest-running, I believe.

From an artistic standpoint, I can't think of anyone currently in the industry outside of our own John Byrne who is capable of producing artwork for 99 consecutive issues of a series in the same time that Mark Bagley has.  He gets high accolades from me for that.

Chuck Wells: Before Bendis and Bagley start crowing too loud about their supposed eclipse of Lee & Kirby on an extended run for a M***** title...

Please point me to the article or interview where either of these guys is crowing about one-upping Stan and Jack.

Like 'em or don't, but until you have proof, plese stop putting words in other people's mouths.  That's how nasty rumors get started.
