LOS ANGELES — For the first time since the 1990s, the Academy Awards telecast will have the same host for two years in a row: Jimmy Kimmel said on Tuesday that he would return as M.C.

“If you think we screwed up the ending this year, wait until you see what we have planned for the 90th anniversary show!” Mr. Kimmel said in a statement, a reference to the bungled best-picture announcement at the culmination of the most recent ceremony. (“Moonlight” won, but an envelope mix-up first led to the accidental coronation of “La La Land.”)

The Academy of Motion Picture Arts and Sciences also said that the producers of the last telecast, Michael De Luca and Jennifer Todd, would return. “Our Oscars team this year delivered a show that hit every high note,” Dawn Hudson, the academy’s chief executive, said in a statement.

Not every one: The ceremony, held on Feb. 26 and broadcast on ABC, attracted roughly 32.9 million viewers, a 4 percent decline from the previous year, according to Nielsen data. It was the smallest Oscars audience since 2008.
