For the first time ever, GLAAD has issued three marks of "Excellent" in their eighth annual Network Responsibility Index (NRI), recognizing LGBTQ-inclusiveness.

According to the Associated Press, GLAAD advocates for gay, lesbian, bisexual and transgender characters appearing in television programs. ABC Family and MTV each got their second "Excellent" marks, while HBO garnered its first.

Leading the way for ABC Family are shows like "The Fosters" and "Pretty Little Liars," with the latter depicting a lesbian couple raising a family of foster children. One of the women also is divorced and has a biological son with her ex-husband.

"To be relevant to our audience, we must reflect the world as they experience it, and we know that experience is based on valuing loving relationships, no matter the gender. This acknowledgment is especially gratifying because it means we are representing their view accurately," Tom Ascheim, president of ABC Family, said in a press release from GLAAD. "We will continue to deliver programming where differences are acknowledged and celebrated."

While ABC Family caters to an audience with a wider age range, HBO represents LGBTQ issues with more adult programs like the wildly popular "Game of Thrones," or the movie "the Normal Heart."

The new study found that 31 percent of HBO's programming hours were LGBTQ-inclusive. "Game of Thrones" gave that figure a nice bump thanks to Pedro Pascal's critically acclaimed portrayal of Oberyn Martell, a fictional prince famous for his bisexuality and love of fighting. "The Normal Heart" also took on a major issue in the gay community, telling the story of the origin of AIDS in the 1980s.

"This recognition from GLAAD belongs to those in the writing room, on set and in the editing bay but we are honored to be their partner and provide a home where they can tell their stories," Michael Lombardo, president of HBO Programming, said in the release. "At HBO we feel if we are not telling diverse stories then we are missing out on some of the best stories. It is a part of our history and an ongoing commitment."
