Originally, Future World debuted with six pavilions: Spaceship Earth, CommuniCore, Imagination!, The Land, Universe of Energy, and World of Motion. The Horizons pavilion opened the following year, and The Living Seas and Wonders of Life pavilions were added in 1986 and 1989, respectively, bringing the lineup to nine. CommuniCore, World of Motion, Horizons, Wonders of Life, Universe of Energy, and Innoventions closed in 1994, 1996, 1999, 2007, 2017, and 2019, respectively. The Fountain of Nations, a large circular musical fountain, was closed in 2019 as well. Each pavilion was initially sponsored by a corporation which helped fund its construction and maintenance in return for the corporation's logos and some marketing elements appearing throughout the pavilion.
