Mr. Pop History – I make it a point not to look at Wiki, so here’s what I have:
Marvel comic book “X-Men” debuted in 1963, almost went away during the 1970’s,
then went on to an incredible peak during the 1980’s with 400,000 readers. What revived them? The addition of new heroes – most notably Wolverine and Storm.

X-men creators are writer Stan Lee and artist Jack Kirby. And, the first X-Men movie came out in 2000
