If we're to define what 'age' comics are in now, I guess we need to look at how long previous 'Ages' have lasted.
The 'Golden Age' was when big, bold, colourful & all-powerful heroes like Superman first arrived. It started around the late 1930's... If we're to believe Wikipedia, the 'Silver Age' which followed didn't start until 1956. So the Age of the golden oldies lasted for just over a decade.
The 'Silver Age' ushered in a new brand of story-telling by the likes of Stan Lee, Jack Kirby & Steve Ditko (to name just a few). It was the notable rise to fame for all of Marvel's established teams. It was an era that apparently ended in the early 70's. So again, this 'age' lasted for approximately 10-15 years.
Then came the lesser known 'Bronze Age'. A time when change was introduced into comics. The rise of Chris Claremont & the X-Men. The Dark Phoenix saga, adventures in space, and gritty characters like Wolverine became popular. It was much shorter lived than any previous age, and tends to be over-looked... or even consolidated into the following era.
The 'Modern Age' started in the early-to-mid 80's. It has seen the rise of big guns & bigger muscles. Women were stereotyped for their mighty endowed T&A, while men were endoward with their mighty steroids. It has been over 25 years since the start of the 'Modern Age'. Over 30 if you discount the short-lived 'Bronze Age'. It really IS time for a new Age of comics.
While bodily proportions have settled down a little, the stories are still as dark & violent for the majority of the time. Things are very dark most of the time. While tidying up my old X-Men related mini series I stumbled across the WoldCATS/X-Men cross-overs from over 10 years ago. It was a series of 4 one-shots named after the Ages, with 3 set in the past & 1 set in the future... Golden, Silver, Modern & Dark. The Dark Age was set in a broken down future, not far-fetched from the Days of Future Past.
I think they were on to something. Stories are much darker. We have titles aimed at mature audiences from both DC (Vertigo) and Marvel (MAX). Since the likes of Grant Morrison have written mainstream titles like New X-Men & JLA, the dark & gritty story lines have become increasingly popular. So yeah, I'd say that this is the 'Dark Age' of comics.
