NBC’s “Today” show having beat ABC’s “Good Morning America” four of the past five weeks among 25-54 year olds viewers who are the currency of news show ad sales, “GMA” was particularly happy to announce Robin Roberts would be back in time for the last week of the February sweep ratings race.

“GMA” host George Stephanopoulos made the announcement on Thursday’s show, and no less than Hillary Clinton, Denzel Washington, Sally Field, Bradley Cooper, Jennifer Lopez and the cast of “Modern Family” weighed in with taped congrats to Robin on her return. Which also will happen just four days before ABC’s broadcast of the Academy Awards, pretty much insuring a “GMA” ratings victory — sorry, “Today.”

It was one year ago at the Oscars that Roberts said she started feeling badly, and one of her stated goals was to be back in time for this year’s Academy Awards, which are broadcast annually on ABC.

Roberts began medical leave from the show in August in order to undergo a bone marrow transplant after being diagnosed with myelodysplastic syndrome (MDS), a rare blood disorder that affects bone marrow; the condition likely was caused by treatment for breast cancer five years earlier.

“GMA” put an end to “Today’s” 16-year weekly ratings winning streak last April (last July among 25-54 year olds).

This season, “GMA” has averaged more viewers than “Today” every week. But “Today” has clawed its way back in the key age bracket and has won that derby four of the past five weeks for which ratings are available.
