Weekly Shonen Jump

Weekly Shonen Jump (週刊少年ジャンプ) is a weekly magazine published in Japan by Shueisha under the "Jump" line of magazines.

The first issue was released with a cover date of July 2, 1968, and it is still circulating. One of the longest-running manga magazines in Japan, it has a circulation of 2.8 million copies (2009). The chapters of series that run in Weekly Shonen Jump are collected and published in tankōbon volumes under the "Jump Comics" imprint every two to three months. The manga series within the magazine target young male readers and tend to consist of a large number of action scenes and a fair amount of comedy.

JoJo's Bizarre Adventure was originally serialized in Weekly Shonen Jump from 1987 to 2004. In 2005, the series changed the magazine of its publication to Ultra Jump during the run of its seventh installment, Steel Ball Run.

History
Weekly Shonen Jump was launched by Shueisha on July 2, 1968 to compete with the already-successful Weekly Shonen Magazine and Weekly Shonen Sunday. The Weekly Shonen Jump's sister publication was a manga magazine called Shonen Book, which was originally a male version of the short-lived shojo manga anthology Shojo Book. Prior to issue 20, Weekly Shonen Jump was originally called simply Shonen Jump as it was originally a semi-weekly magazine. In 1969, Shonen Book ceased publication at which time Shonen Jump became a weekly magazine and a new monthly magazine called Bessatsu Shonen Jump was made to take Shonen Book's place. This magazine was later rebranded as Monthly Shonen Jump before eventually being discontinued and replaced by Jump Square.
