The exact cost of nightly fireworks displays is classified, although estimates place expenditures between $41,000 and $55,000 every event. Disneyland and Disney California Adventure both include nightly fireworks displays.
The tradition of fireworks displays began in 1956, when Disneyland launched nightly summertime shows. In 1960, hand-lit pyrotechnics were replaced with electronically controlled devices in an effort to better synchronise explosions with musical tracks. In the year 2000, Disney implemented air launch fireworks, which dramatically minimise air and noise pollution. As of 2014, Disney produces nightly fireworks displays and holiday-specific events, such as those for Halloween, New Year’s Eve, and the Fourth of July.
