Some Shoshinkai and Space World events served as epicenters of some of the most intense anticipation within the video game industry of the late 1990s and the 2000s. At these shows, Nintendo launched the Super Famicom, GameCube, Game Boy Advance, Nintendo 64, 64DD, and all the core games at the time within the "Super Mario", "The Legend of Zelda", and "Pokémon" franchises. Some events showed exclusive videos, playable previews, and live technology demos of vital video game material that would never be seen again, leaving fans and press to build hype and intrigue for years. Ever since, video game historians would mine remnants of papers, video clips, interviews, and software from the show's corpus of media materials. This would be gleaned from trade press coverage at the time, revisited in celebrity developer interviews over the years, and from artifacts discovered in the world's secondary markets over the decades.
