DBZ and Rurouni Kenshin really got me into watching anime. eventually i got into a wide variety of others like the Gundam series and Yu Yu Hakusho and Tenshi Muyo.
I watched Sailor Moon back in early high school which was about six years ago. I didn't watch any others until recently. My friend got me into manga because she let me borrow her fruits basket books. So then I decided to watch some anime. Started out rewatching Sailor Moon again (the first two season) and now I've been checking out tons more!
I've been watching anime since I was really, really little ... but I never KNEW it was anime. What made me start to get in to the genre was when the Sailor Moon dub started airing here back in 1995/1996. I've never looked back!
For me, it was Inuyasha on Adult swim late at night. It was a really good one at the time and once I got the internet, I started watching Naruto as well. Actually, Naruto got me into the violent anime. lol
I never really noticed a line. When I was little I watche CCS and Sailor Moon, and Simply continued on from there. The thought of not watching anime never really crossed my mind.
