Carl Laemmle opened his 230-acre Universal City ranch to visitors on March 15, 1915, but the advent of sound in motion pictures forced the studio to close the lot to visitors within a few years.
Universal reopened its lot to visitors in 1961, outsourcing the tours to the Gray Line bus company. But, following a feasibility study by Buzz Price — the same man who helped determine the locations for Disneyland and Walt Disney World — Universal decided to start its own tram tour of its facilities, and Universal Studios Hollywood opened on July 15, 1964. Last year, the park welcomed more than nine million visitors.
