Following the advent of television and the Paramount Case, the major studios attempted to lure audiences with spectacle. Widescreen processes and technical improvements, such as Cinemascope, stereo sound, 3-D and others, were developed in an attempt to retain the dwindling audience by giving them a larger-than-life experience. The 1950s and early 1960s saw a Hollywood dominated by musicals, historical epics, and other films which benefited from these advances. This proved commercially viable during most of the 1950s. However, by the late 1960s, audience share was dwindling at an alarming rate. Several costly flops, including "Cleopatra" (1963) and "Hello, Dolly!" (1969) put severe strain on the studios. Meanwhile, in 1951, lawyers-turned-producers Arthur Krim and Robert Benjamin had made a deal with the remaining stockholders of United Artists which would allow them to make an attempt to revive the company and, if the attempt was successful, buy it after five years.
