Only one of this year's categories, supporting actor in a drama, lacked any performers of color. NBC was a distant third with 78, a figure that put it first among broadcast networks.
"It has been another exceptional year in television marked by extraordinary storytelling from a wealth of diverse and innovative content creators", Television Academy Chairman and CEO Hayma Washington said in a statement.
"Game of Thrones" may lead the pack with 22 Emmy nods this year, including one for Outstanding Drama Series, but Clarke and Harrington weren't among the recipients. It was also the first time Apple Inc. was nominated, for its CBS collaboration "Carpool Karaoke".
The top comedy nominee is Donald Glover's Atlanta, with 16.
Besides the repeat nomination for Dowd, "The Handmaid's Tale" scored nods for Drama Series, Actress in a Drama Series (Elisabeth Moss), Supporting Actor in a Drama Series (Joseph Fiennes), and two additional nominations for Supporting Actress in a Drama Series (Alexis Bledel and Yvonne Strahovski).

Both men are nominated again, along with noteworthy first-timers including Latino actors Ricky Martin and Penelope Cruz for "The Assassination of Gianni Versace: American Crime Story", Tiffany Haddish for "Saturday Night Live", Issa Rae for "Insecure" and John Legend for "Jesus Christ Superstar Live in Concert". Although it's up for top series honors, it drew only three supporting actor bids for cast members Lena Headey, Nikolaj Coster-Waldau and Peter Dinklage.
Other streaming services also received nominations for their originals, including Hulu with 27 nominations, with The Handmaid's Tale defending its Best Drama award this year.
The nominees for best drama series were The Handmaid's Tale; Game of Thrones; This Is Us; The Crown; The Americans; Stranger Things; and Westworld.
