Broadway legend Kristin Chenoweth and NBC Entertainment Chairman Robert Greenblatt were honored for their gay rights advocacy at Sunday night's GLAAD Media Awards in Los Angeles.

The Gay & Lesbian Alliance Against Defamation's (GLAAD) 22nd Annual Media Awards show was co-hosted by Amy Poehler and Rashida Jones, stars of the NBC comedy Parks & Recreation.

Special guest Dolly Parton presented the Stephen F. Kolzak Award to Greenblatt, whose work has included two groundbreaking gay dramas – Queer as Folk and The L Word. The award recognizes an openly gay media professional who has made a significant difference in promoting equality for the LGBT community.

“I'm very grateful to everyone at GLAAD for thinking of me for this honor,” Greenblatt said in accepting the award. “I salute all the producers, writers, network executives, and actors who took on the issue and broke ground way before I did --- and who continue to do it today. Many of you are in the room tonight. I share this award with you. While we still have a long way to go, we have made great strides both politically and in our media. May that not only continue, but increase in velocity… because we can help change the way the world thinks about LGBT people, not to mention how LGBT people think about themselves.”

Sean Hayes presented the group's Vanguard Award to Chenoweth, an outspoken advocate for gay rights.

“I want to encourage many people of all faiths to come forward and stand with me,” Chenoweth said in her remarks. “Even if you don't believe in Jesus the way I do, he did teach love -- not just tolerance, but acceptance. I'm lucky I had parents who adopted me at birth, conservative Southern Baptists who said, 'You will love everyone the same' … Mostly I would like to thank GLAAD for this amazing, amazing honor. This is the biggest honor I have ever received.”

Prime time comedies Glee and Modern Family tied to win the outstanding comedy award.
