NEW YORK — CBS’ new “Early Show” got off to a solid ratings start Monday, but the day’s big winner was NBC’s Mariah Carey-boosted “Today.”

The live concert set by the pop star lifted the usually dominant Peacock program to a 5.8 rating/19 share, according to 44-city overnight Nielsen data released Tuesday.

The “Early Show,” co-hosted by Bryant Gumbel and Jane Clayson, registered a 3.0 rating/10 share, according to 46-city overnight Nielsen data released by CBS News. That’s a 20% increase from what the old “CBS This Morning” averaged in the slot a week ago.

Carey was scheduled to appear on the “Early Show,” but backed out late last week after CBS failed to come through with the proper permits required for an outdoor concert.

ABC’s “Good Morning America” earned a 4.0 rating/13 share, according to the 44-city overnight Nielsen data.

“Today” was no doubt helped by Carey and the flurry of publicity that surrounded her shift from CBS to NBC. The Peacock ayemcast’s numbers also benefited from the fact that Monday was a huge news day, filled with breaking info about the EygptAir plane crash. “Today” tends to get a boost on big news days.

National Nielsen data should be available today.
