Emmy Awards 2015: Complete list of winners from 'Game of Thrones' to Viola Davis and Jon Hamm

The 67th annual TV Emmy Awards was a big night for HBO, as its epic "Game of Thrones" won its first Best Drama award on Sunday night at the Microsoft Theater in Los Angeles.

"Game of Thrones" beat four-time winner "Mad Men" in the Best Drama category and also took home the awards for writing, directing and for supporting actor Peter Dinklage. In the comedy category, HBO's "Veep" beat "Modern Family," which had been a big winner the past five years.

"Veep's" Julia Louis Dreyfus won Outstanding Lead Actress in a Comedy Series Emmy, marking her total Emmy awards count to four.

Actor Jon Hamm took home Outstanding Lead Actor in a Drama series for the final season of “Mad Men” while “How To Get Away With Murder's” Viola Davis became the first black woman to win Outstanding Lead Actress in the same category.

"There's been a mistake, clearly," Hamm said about his fellow nominees. "It's impossible to be named with all of those extraordinary gentlemen."

"The only thing that separates women of color from anyone else is opportunity," Davis said in her emotional acceptance speech. "You cannot win an Emmy for roles that are simply not there."

Actor Jeffrey Tambor won Best Actor in a comedy for his role as a transgender in Amazon's "Transparent." The actor dedicated his award to the transgender community. "Thank you for your courage. Thank you for your stories. Thank you for your inspiration," he said.
