In 1975, an amendment to the Prime Time Access Rule gave the Sunday 7:00 pm Eastern Time slot back to the networks, allowing NBC to move "Disney" back by a half-hour. It also allowed CBS to schedule "60 Minutes" at 7:00 pm Eastern Time starting on December 7; prior to this, "60 Minutes" had aired at 6:00 pm Eastern and did not begin its seasons until after the National Football League season ended. "Disney" fell out of the top 30, while "60 Minutes" had its ratings rise significantly.
