Original Yu-Gi-Oh! creator Kazuki Takahashi first tried to break into the manga business in 1982, but success eluded him until Yu-Gi-Oh! debuted in the Japanese Weekly Shonen Jump magazine in 1996. Yu-Gi-Oh!'s themes of friendship and competition, together with Takahashi's weird and wonderful art, soon became enormously successful, spawning a real-world card game, video games, and six anime series (two Japanese Yu-Gi-Oh! series, Yu-Gi-Oh! GX, Yu-Gi-Oh! 5D's, Yu-Gi-Oh! Zexal, and Yu-Gi-Oh ARC-V).
