Before the Rose-led trio arrived, CBS averaged 2.44 million viewers in the morning during the 2011-12 TV season, according to Nielsen. ABC’s “Good Morning America” is the ratings leader with 4.4 million viewers but lost nearly 1 million over that period. Part of the premium that CBS was getting for its ad time on “CBS This Morning” can be credited to Rose. As CBS News employees absorbed the shock and suddenness of his firing, some wondered how that prestige that Rose provided will be replaced. The shake-up of any TV morning team usually results in a shift in the audience, which grows used to waking up to the same faces every day.
