How many manga series have been in shonen jump not including perviews?
I remember reading: Dragon Ball Z, Sandland, YuYu Hakusho, Yu-Gi-Oh!, Hikaru No Go, Yu-Gi-Oh! Millenium World, Yu-Gi-Oh! GX, Shaman King, One Piece, Bobobo-Bo Bo-Bobo and Bleach. So as far as I can recall: 10 (or 8 if you count all the Yu-Gi-Oh as one thing).
