Do all published manga originate from one-shots?


I heard that some popular manga (for example - Naruto, Nurarihyon no Mago,
Beelzebub) are published as one-shots during their first try. I want to know
if that applies to all manga or not? Would many manga be published as a one-
shot first?




It doesn't apply to all manga. For instance there's manga that are adaptations
of other works (anime, video games, light novels) which don't start off as
one-shots and have, at the very least, a contractual run. Additionally, there
are also manga that are used originally as promotional, as advertisement for a
store or an upcoming anime.

The Evangelion manga is an odd-ball, where it was supposed to be an adaptation
of the Neon Genesis Evangelion anime series, and start a month or two before
its TV run as a promotion for the anime, but the TV run was delayed and didn't
actually air until a year's worth of manga chapters. Additionally, there's
several recent spin-off manga loosely based on the series.

There's a bunch of Gundam manga that were adapted from anime that were never
one-shots. Slayers has several manga series that were adapted from the anime
and light novels. Cowboy Bebop, Blade of the Immortal, etc.
