The show's continued ratings success in the post-Walt era came to an end during the 1975–76 season. At this time, Walt Disney Productions was facing a decline in fortunes due to falling box-office revenues, while NBC as a whole was also slipping in the ratings. The anthology series became even more dependent on airings of live-action theatrical features, its "True-Life Adventures", reruns of older episodes, and cartoon compilations. Nothing from the Disney animated features canon aired, with the exceptions of "Alice in Wonderland" and "Dumbo", as part of a long-standing policy placed on the program by Disney. Additionally, in 1975, when CBS regained the broadcast rights to the 1939 Metro-Goldwyn-Mayer film "The Wizard of Oz", it was scheduled opposite "Disney", as it had been between 1960 and 1968. At that time, telecasts of that film were highly rated annual events, which largely attracted the same family audience as the Disney series. From 1968 to 1975, when NBC held the television rights to "Oz" (which it had acquired from CBS in 1967), it usually pre-empted "Disney" to show it. However, the show's stiffest weekly competition came from CBS's newsmagazine "60 Minutes".
