Construction began on the Walt Disney World park in Florida, on land that had been
purchased incrementally by Disney for the better part of a decade.

Disneyland Park, as it is known today, is located in Anaheim, California and is owned 
and operated by the Walt Disney Parks and Resorts division of The Walt Disney  
Company. Construction began in 1954 and the park was unveiled during a special  
televised press event (below) on the ABC Television Network on Sunday, July 17,
