Disneyland celebrated its 50th anniversary Sunday, with a fireworks and confetti display outside the Sleeping Beauty Castle and televised images of the park's launch in 1955.

"Dad's vision called for this, for Disneyland, to be something that could grow more beautiful every year, and it has," said Diane Disney Miller, one of founder Walt Disney's two daughters.

Governor Arnold Schwarzenegger attended, and praised the theme park's contributions to the state's economy.

Disneyland was extremely innovative, and had little competition, when it opened on July 17, 1955. It used robotic figures, holographs and panoramic movies. Over the years, it has pioneered new technology on rides such as "Space Mountain" in Anaheim and "Mission Space" at Epcot in Orlando, Florida.

Disneyland has also recieved a star near the Hollywood Walk of Fame, to comemmorate the event.
