Then I thought, what are the important anniversaries? I know there won't be a consensus, but I thought I'd ask.

10 would certainly be one. If a title can notch up a decade, that's worth commemorating, I would have thought.

I'd say 25 is definitely worth commemorating. That's a quarter of a century.

And 50 would seem worth commemorating, too. Half a century after all!

So, 10, 25 and 50 would seem to be important milestones, worth recognition via a topic, special issue, magazine article, etc.

But what about other numbers? Should 20 be important? Or not, given 25 is a milestone?

What about 60? 65? Is one more important than another? Should we skip 60 and just wait for the 65th anniversary of something?

Beyond that, I'd say 75 is important. After that, well I guess 100 is. But 90 would seem impressive, too. At the same time, commemorating the 90th anniversary of something seems redundant as it seems more worthwhile to wait for the centenary. 

Any views?

I can recall a couple of long running magazines that did something commemorating 60 years. TIME reached that milestone in 1983, and published a special issue, which covered significant events, although not necessarily in chronological order. 

TV GUIDE was pretty much on its last legs for its 60th anniversary, in 2003, and just did a bunch of fakey-collectible 'special' covers.

And as we close in on March, I'm sure we've all heard about the incredible celebrations DC has for Superman's 80th anniversary. Hmm? No? Nothing?

Well, I KNOW we know about Marvel's big 55th birthday party for the Avengers, yes? No? Marvel hasn't done anything, either?

Robbie, I don't think there is any interest in such anniversaries anymore, I'm afraid. Shucks, I suspect that DC and Marvel celebrate every issue that isn't below the cancellation level. Their sense of history doesn't past a month or two, I suspect.

I'd love to see some celebrations!
