'How beauteous mankind is! O brave new world,' - William Shakespeare, The Tempest.
Odorama was first introduced in the film Polyester (1981) by John Waters using scratch-and-sniff technology. Audiences were given cards when they entered the cinema, each with 10 different scents, marked and numbered. At various points in the movie, a number would flash onscreen, the cue for the audience to scratch the corresponding scent. Odorama was born and was used in several movies at the time. It seems logical to assume it would be introduced in the Brave New World. Huxley remarked about "man's almost infinite appetite for distractions" and he held the view that people are controlled by those that inflict pleasure not pain.
