Walt Disney was the first filmmaker to explore the idea of actually including scents with his 1938 film Fantasia, but eventually decided against pursuing this for cost reasons.
In the 1980s, Disney publically announced a newly-designed "Smellitzer" system that’s still in use today. The system was created by Bob McCarthy. The system, featured in dozens of Disney rides across the world, blasts smells up to 200 feet across a room in a ride using air-canon technology. The smells exit via exhaust systems and are computer-controlled to go off when a new set of riders approach.
