I grew up watching Gundam wing, sailor moon, Tenchi and outlaw star (probably more but can't quite remember) without realizing it was anime. Other than sailor moon (and yes I know it was aimed towards girls but oh well) I thought all these shows were just for adults as I could only watch them on sky and not on normal telly. I would stay round my nans over the weekend, stay up late and watch whatever came on at night on toonami or foxkids etc. When we got our first pc with decent internet the first show that made me start looking at anime specifically was escaflowne and the first show I watched knowing full well it was anime was Evangelion (which was also my first physical copy). Been hooked on it ever since.
