Champion Carnival
From 1959 to 1972, the Japan Pro Wrestling Alliance (JWA), run by Rikidōzan, held a tournament called World League (also known as the "World Big League"), which featured both Japanese and foreign professional wrestlers. Rikidōzan himself dominated the annual tournament early on, however, after his death in 1963, the tournament was won six times by Giant Baba and once by Antonio Inoki. JWA folded shortly after both Baba and Inoki left the promotion to create All Japan Pro Wrestling (AJPW) and New Japan Pro-Wrestling (NJPW), respectively. Both men took the concept of World League with them to their new promotions, with Baba creating the "Champion Carnival" in 1973 and Inoki creating the World League in 1974, later renaming it G1 Climax.
New World Order (professional wrestling)
The nWo storyline was an idea created by WCW Executive Vice President Eric Bischoff, whose inspiration for the angle came after attending New Japan Pro Wrestling's Battle Formation show at the Tokyo Dome on April 29, 1996. The show was headlined by a NJPW vs. UWFi match for the IWGP Heavyweight Championship, as New Japan's Shinya Hashimoto defeated UWFi's Nobuhiko Takada. Bischoff wanted to do an invasion-type angle where WCW was being sabotaged by another wrestling group, initially insinuated as being the WWF, since the nWo's founding members had previously wrestled for the company. The nWo was originally portrayed as a separate entity from WCW. Often, propaganda-style vignettes and product commercials concerning the nWo were presented in the style of a broadcast signal intrusion, with a voice proclaiming, "The following announcement has been paid for by the New World Order". Others, such as Kevin Nash, television director Craig Leathers, chief WCW booker Terry Taylor, and Taylor's assistants Kevin Sullivan and Paul Orndorff, all contributed their own ideas to the nWo concept.
