Thirteen shows received 11 or more nominations.
The nominations were announced Thursday by actress Kerry Washington and late-night host Jimmy Kimmel, who stepped in at the last moment to substitute for "Parks and Recreation" star Nick Offerman, who couldn't make it because of bad weather.

Last year's winners for Outstanding Comedy and Outstanding Drama -- "Modern Family" and "Mad Men," respectively -- are once again nominees in those categories.
"Downton Abbey" won for Outstanding Miniseries or Movie last year but this year was nominated in the drama category.
HBO had a strong presence in the comedy series category, with three of its shows nominated: "Curb Your Enthusiasm," "Girls" and "Veep." The other nominees for comedy series were "30 Rock" and "The Big Bang Theory."
The rest of the nominees for drama series were "Breaking Bad," "Boardwalk Empire," "Homeland" and "Game of Thrones."
HBO led all outlets with 81 total nominations. For the major networks, CBS had the most nominations with 60, while ABC had 48, NBC had 51, and Fox had 26.
