The title W.I.T.C.H. is an abbreviation of the first letters of the main characters' names: Will, Irma, Taranee, Cornelia, and Hay Lin.
W.I.T.C.H. was originally published in Italy, and is currently being published in over fifty countries and translated into over twenty different languages around the world.
For unknown reasons, the comic was never published in Japan, and instead a manga based on the comic, with art by Haruko Iida (飯田晴子, Iida Haruko?), was published by Kadokawa Publishing (角川書店, Kadokawa Shoten?) in their monthly magazine Asuka Monthly (月刊あすか, Gekkan Asuka?) and later collected in two Tankoban volumes, upon which the comic was canceled. The paperback volumes had covers by Daisuke Ehara (江原大介, Ehara Daisuke?).
