Weekly Shōnen Magazine

Weekly Shōnen Magazine (週刊少年マガジン) is a weekly shōnen manga magazine published on Wednesdays in Japan by Kodansha, first published on March 17, 1959. The magazine is mainly read by an older audience, with a significant portion of its readership falling under the male high school or college student demographic. According to circulation figures accumulated by the Japanese Magazine Publishers Association, the magazine's circulation has dropped in every quarter since records were first collected in April–June 2008. This is, however, not an isolated occurrence as digital media continues to be on the rise.

It is one of the best-selling manga magazines. By March 2008, the magazine had 2,942 issues, having sold 4.55billion copies, with an average weekly circulation of 0. At an average issue price of ¥ ($), the magazine had generated approximately ¥billion (US$billion) in sales revenue by March 2008. In addition, about 1 billion compiled tankōbon volumes had been sold by March 2008.

Jason Thompson stated that it is "more down-to-earth, as well as just a tad more guy-oriented" compared to Weekly Shōnen Jump and likened this magazine to "more like something you'd find in the guys' locker room."

Series
There are currently 25 manga titles being serialized in Weekly Shōnen Magazine. Out of them, Ahiru no Sora is on hiatus.

It runs original manga created for the site as well as manga moved from one of the print magazines related to Weekly Shōnen Magazine. It opened on August 3, 2015.

Reception
The Weekly Shōnen Magazine achieved success in the 1970s and subsequently had increased sales. As a result, it became the top-selling manga magazine in Japan of its period, appearing popular amongst many otaku. But the position was later occupied by Weekly Shōnen Jump, when this competitor was born in 1968, knocking Shōnen Magazine off the top spot. Shōnen Jump had begun to circulate and dominate the manga magazine market. This started from the 1970s and continued throughout the 1990s.

In October 1997, Shōnen Magazine reclaimed its position as the top-selling manga magazine of its day until this was brokered in 2002. Currently, the two magazines have competed closely in terms of market circulation. Sales of the two magazines now remain very close. Circulation has dropped below two million. In a rare event due to the closeness of the two magazine's founding dates, Weekly Shōnen Magazine and Weekly Shōnen Sunday released a special combined issue on March 19, 2008. In addition, other commemorative events, merchandise, and manga crossovers were planned for the following year as part of the celebrations.

Others include Shōnen Magazine, published by Kobunsha of the same Kodansha group. Shōnen Magazine famously serialized Tetsujin 28-go, the first mecha anime from July 1956 to May 1966.
