Theme parks, television and other interests: 1950–1966 In early 1950, Disney produced Cinderella, his studio's first animated feature in eight years. It was popular with critics and theater audiences. Costing $2.2 million to produce, it earned nearly $8 million in its first year. Disney was less involved than he had been with previous pictures because of his involvement in his first entirely live-action feature, Treasure Island (1950), which was shot in Britain, as was The Story of Robin Hood and His Merrie Men (1952). Other all-live-action features followed, many of which had patriotic themes. He continued to produce full-length animated features too, including Alice in Wonderland (1951) and Peter Pan (1953).

In March 1952 he received zoning permission to build a theme park in Burbank, near the Disney studios. This site proved too small, and a larger plot in Anaheim, south of the studio, was purchased. To distance the project from the studiowhich might attract the criticism of shareholdersDisney formed WED Enterprises (now Walt Disney Imagineering) and used his own money to fund a group of designers and animators to work on the plans; those involved became known as "Imagineers". After obtaining bank funding he invited other stockholders, American Broadcasting-Paramount Theatrespart of American Broadcasting Company (ABC)and Western Printing and Lithographing Company. In mid-1954, Disney sent his Imagineers to every amusement park in the U.S. to analyze what worked and what pitfalls or problems there were in the various locations and incorporated their findings into his design. Construction work started in July 1954, and Disneyland opened in July 1955; the opening
