Good morning news at ABC, CBS; not so much at NBC

NEW YORK – Even as “Good Morning America” solidifies its status as the most popular morning program, ABC isn’t the only network where executives have been smiling lately.

The “CBS This Morning” broadcast is actually growing at a faster rate, according to the Nielsen ratings company’s measurement of viewers during May.

The CBS telecast, though, remains in third place behind “Good Morning America” and NBC’s struggling “Today” show.

It’s a remarkable time of viewer experimentation at a time of day when habits are often quite difficult to break.

That has to be encouraging to CNN, which premieres its “New Day” morning program in two weeks.

During a newsy month, “Good Morning America” averaged 5.7 million viewers, an increase of 10 percent from 2012.

Its nearly million-viewer lead over “Today,” at 4.78 million, represents a dramatic shift; in May 2012, the two telecasts were nearly tied, with “Today” holding a slight lead.
