Shounen Jump is the biggest and best-selling manga magazine in Japan, and one of the best-selling magazines of any type in the whole world. Its circulation is around 5 million a week, in peak moments it was 6 million a week. After the disparison of some hit-series like Dragonball and Yuu Yuu Hakusho, Shounen Jump has had for the first time since long declining sales figures.
Over the years a continuing stream of hit-series have emerged from Shounen Jump: Dragonball, Slam Dunk, City Hunter, Dr. Slump, Cat's Eye, Video Girl, Yuu Yuu Hakusho, Kochi Kame... Apparently Jump has found itself a unbeatable successformula. That was necessary to survive and become the biggest, because it was not the first Shounen magazine in existence. Founded only in 1968, which means that its direct competitors already had a lead of many years. What is the success formula employed by Jump? It has encouraged young and unknown artists to work for them and it has nurtured them until they became famous. It's stories are mainly based on three principles: FRIENDSHIP, EFFORT, VICTORY.
There are in fact a large number of magazines that have sprouted from the original Shuukan (weekly) Shounen Jump: Gekkan (monthly) Shounen Jump, Super Jump, Business Jump, Young Jump, V-Jump. Each of them have an other target audience in the male side of the readers.
