Well, you can also make this argument about anime. Anime in the US had for a long time been seen as just cartoons. Even today people try to lump it together with our sad pathetic american cartoons. Cartoons today don't even compare to what anime is in japan. Right now in the US the only decent stuff we get is from pixar and some few good ones (avatar comes to mind). I've loved anime for about 16 years now, and the whole thing has changed alot in those years. The old days of bootlegged tapes and spotty subtitles eventually led to the dubbed era. We got releases in both english and japanese w/subtitles, and we were more than happy to pay 30 bucks for two episodes of tenchi. The standard 26 episode series was usually released in 8 tapes. This is generally based off the tape legnth, with 4 episodes being a long tape. When DVDs started to come out this was an accepted practice for a while as well, with the exception of ADV who liked to pull some crap with 2 or 3 episodes per dvd for a 10 dvd 26 episode series... yeah, bad ADV, you suck! Eventually it became commonplace to get 4-6 episodes on a dvd with a bunch of extras. Sometimes we would get a 26 episode series on 3 dvds, but that was rather rare and usually those series were kinda lame.
Meanwhile fansubbers went from sending tapes around the country to getting the anime raw digitally and putting the subs either in soft or hardsub format. This is where we get back to the decade of the nerd. Fansubs made by nerds pretty much made a WHOLE lotta anime known in the states. For a long time certain series were only known by their fansub version. One Piece went for the LONGEST time without a release in the US, and that was horribly botched. The funimation version that took over is soooooooooo much better. I support my fansub community, but I also buy the anime I like when it comes out here on dvd. I'm an anime fan, but that's only one facet of my nerd persona.
Really, I turned to anime as a natural progression from my love of D&D and fantasy novels. My early anime collection included Slayers, Record of lodoss war and anything else that looked fantasy type. From there I got hooked on the Irresponsible captain tylor, Evangelion, Ramna 1/2, Cowboy Bebop and others. Suddenly I found myself reading science fiction and watching it on tv as well. I found that anime became a gateway drug to broaden my nerd profile.
Hell, even these days I would say that anime is a nessesity in being a nerd. Even though it's not completely accepted by modern society, you find it alot more than you did back in the late nineties. If you were to walk around in Cosplay back then you would definately get alot of stares and maybe police would be sent after you. Today people take pictures and ask you how you got it made. The anime convention has become a mainstream nerd event. Suddenly, male and female nerds are meeting together in real life. The bleak future of idiocracy may actually be averted. That's just my 2 cents.
