Of all the things that conveyors have moved the past 222 years, none is more iconic than the small chocolate candies that overwhelmed Lucille Ball and Vivian Vance working on the assembly line in September 1952.

Since then, several companies have used conveyors to create memorable ad campaigns. One of the most notable was for M&Ms, which featured its large peanut mascot overseeing an industrial conveyor in a plant.
