Kenta Kobashi, Toshiaki Kawada, Mitsuharu Misawa and to a lesser extent, Akira Taue were famous for putting long, "epic" style matches were they would kick out of finishers and made the crowd go apeshyt as they would never know when a match would end. Given how their moves weren't finishing shyt, they started coming up with new, devastating moves to end a match. They followed and made a style that Jumbo Tsuruta, Gen'ichiro Tenryu, Riki Choshu and Akira Maeda created, evolve.
In the US it wasn't about creating new moves but to repeat the same ones. Although that's not that accurate as repetition was also a big part of "King's Road style". The new moves Kobashi, Kawada, Misawa and Taue created were barely used, but when they were indeed hit, the match was over.
