Sunday night, which used to vie with Thursday as the most popular night for TV viewing, is continuing to struggle, with blah ratings coming in week after week for shows that have been mainstays. CBS's 60 Minutes remains an exception -- it was the highest-rated show on Sunday night with 11.35 million total viewers, according to overnight Nielsens. Donald Trump's Celebrity Apprentice, however, was not. It's down more than 35 percent from the same week a year ago to just 4.6 million viewers. ABC, which had hoped to get a lift on Sunday nights from the new series Red Widow, saw the show's audience decline 20 percent to 5.3 million from its premiere a week earlier.
