Pay cable broadcasters HBO and Showtime topped GLAAD's third annual report of gay-inclusive broadcasting, while ABC led the networks for the second year in a row.

HBO scored high marks on the Gay & Lesbian Alliance Against Defamation's (GLAAD) Network Responsibility Index released Monday. The pay cabler positively depicted the lives of gay, lesbian, bisexual and transgender characters in 10 of its 14 original prime-time shows, adding up to 46 percent of LGBT-inclusive hours of original programming during shows such as True Blood, Entourage, and The No. 1 Ladies' Detective Agency. HBO scored 26 percent last year.

Showtime came in second with 26 percent, down from 32 percent last year. The cable network is certain to fall further next season as the L Word, a series that revolves around the lives of a group of lesbians in Los Angeles, has ended its six-year run.

For the report, GLAAD combed through over 6,000 prime-time hours from the five major network broadcasters (ABC, CBS, NBC, Fox and the CW) and 10 prominent cable networks for positive gay themes or characters aired between June 1, 2008 to May 31, 2009.

ABC led the networks for the second year in a row, with 24 percent. Last year's marriage between Kevin and Scotty on Brother's & Sisters helped the network win the top spot. The newlyweds were joined by Uncle Saul's coming out story this year.

NBC and CBS only scored 8 percent and 5 percent, respectively, and received a grade of “failing” from GLAAD.

Last year's winner FX proved the biggest disappointment, dropping 32 percent from last year's 45 percent high.

“FX declined a significant 32% over the past year due largely to the cancellation of several LGBT-inclusive series,” GLAAD said. “FX will need to infuse its remaining series with LGBT content if it is to reclaim its status as the most LGBT-inclusive cable network.”
