By 1966, Tomorrowland was becoming quickly outdated. Most of its attractions were only there as advertisements for various sponsors, such as Monsanto, despite the 1959 Tomorrowland expansion. In 1967, the area was completely rebuilt with new attractions and scenery. The original layout was demolished, with a few exceptions, and a new set of buildings were erected. The addition of the Carousel of Progress, Adventure Thru Inner Space, an improved and larger Circle-Vision auditorium, Flight to the Moon, and the PeopleMover helped give Tomorrowland its "World on the Move" theme.
