CBS will officially start its Sunday prime-time lineup, beginning with 60 Minutes, at 7:30, on those days when there are doubleheader games. That affects both Big Brother and The Amazing Race.
This is very smart and awesome of CBS, which frequently deals with variable delays. The network said in a press release that the days affected this fall are Sept. 16 and 23, Oct. 7 and 21, Nov. 4 and 18, and Dec. 2, 16 and 30.
Earlier this summer, the NFL pushed back start times on the second games by 10 minutes, meaning the delays were likely to get worse.
