So the amount of time that had passed between the release of this comic:

…and this comic:

…is kinda/sorta about the same, give or take a handful of months, as will have passed between the release of this comic:

…and the new
Action Comics #1 coming this September:

First, to save me some “um, actually”-ing in the comments, please note I said “about,” not “exactly.” It’s close enough for my point, or what passes as my point.
Second, it’s a bit “one of these things is not like the other,” I realize, since one is a debut issue and the other two are reboots of one kind or another, though you could read the “Death of Superman” event as an equally-influential revitalization of the franchise.
But when looking at the spans of time involved here…the debut of Superman (and, if not the launch of the Golden Age of Comics, at least its most significant event) in 1938, followed eighteen years later by the launching of the Silver Age* with the debut of the new Flash (itself only seven years after the cancellation of the Golden Age Flash series, and five years after the G.A. Flash’s last appearance in All-Star Comics).
My only point to this really is that, when I was younger, and was first learning about all these events in comics history, it certainly felt like we were talking about longer periods of time. Given all the talk and bandying about of the terms “Golden Age” and “Silver Age,” it came as bit of a shock to realize that only about half a decade separated the two eras. I mean, that’s barely longer than it took Ultimate Wolverine Vs. Hulk to finish.
Conventional wisdom is that the customer base for comics turned over fairly quickly in those days. The kid who bought the last issue of the Golden Age Flash Comics, #104, had probably outgrown comics before Showcase #4 rolled along, and the kids who bought Showcase #4 probably had never seen the previous Flash. I mean, I wasn’t there, and I’m making some assumptions, and I know some people probably carried over from one “Age” to the next. But that was the general belief.
Compare to today, when most people who buy comics have been buying for years at a time. In my case, using the Superman example…I was buying the comic in the early 1980s, I bought the Man of Steel mini in 1986 which restarted Superman’s history from scratch, I bought (and am still buying) all the main Superman series from then ’til now, and I plan on picking up the new relaunched Superman titles in a couple of months. That’s bit of an extreme case, but comic fans following characters or series for years at a time is more the rule than the exception, nowadays. At least, those folks are the primary target of the superhero publishers. The “crossover event leading into the next crossover event” publishing strategy is obviously not one they could have pulled off in, say, 1948, when the audience turnover would have meant people reading the end result of this strategy without having been there at the beginning.
I picked the Death of Superman issue as an example because that’s a relatively recent event that a number of us recall happening during our comics-reading (and for some of us, our comics-retailing) history. It’s a pretty solid timestamp in our memories, a “where were you when…?” kind of thing. (Where was I? Explaining to an enormous and increasingly-irritable crowd of people “uh, only one customer, please.”) It doesn’t seem like that long ago to me, and yet the time that has passed is longer that the original run of The Spirit and the original run of Fawcett’s Captain Marvel.
Boy, this kind of got away from me. Another point I was intended to make was “it was a lot easier to get away with reboots back in the day” because, well, anyone complaining was probably going to stop reading comics soon anyway, and there were always more readers coming to replace them. Yet another point was simply realizing that less tempus had fugited than I thought when it came to certain historical events in the comics industry. That last point is simply the result of age, I’m sure…when I was 15, a five year span sure seemed like an eternity. Today: well, I’m pretty sure I’ve got socks that are older than five years. (Shut up…they’re in good shape!)
But if there were a primary point to all this babbling, it is simply that I was somewhat amused by comparing the two timespans above. And yes, I know not everyone who’s reading this has been reading comics for decades. Let me wallow in my dotage in peace.
* Some people mark the beginning of the Silver Age with the first appearance of the Martian Manhunter. And, y’know, that’s cool with me.
Oh, by the way, all images are from the Grand Comics Database. I was too lazy to dig out my copy of the original Action #1 to scan.
