Main Street Electrical Parade
The predecessor to the 1972 Disneyland Main Street Electrical Parade was the Electrical Water Pageant, a show consisting of fourteen 25-foot-tall (7.6 m) screens decorated with electrical lights and presented on Walt Disney World's Seven Seas Lagoon from 1971 to the present. Not long after the Electrical Water Pageant debuted, Card Walker commissioned the development of what became the Main Street Electrical Parade to provide Disneyland with a similar nighttime visual spectacle. The parade's design used nickel–cadmium batteries, which the Disney movie studio had recently started using, and Italian-made miniature bulbs that Disneyland staff had seen in light displays along Michigan Avenue in Chicago, Illinois. Disney arranged for the parade's original floats to be constructed by Silvestri, the Chicago-based company responsible for those holiday displays.
