Cabler ABC Family topped GLAAD's fifth annual report on gay-inclusive broadcasting, while the CW led the networks.

ABC family scored an “excellent” rating on the Gay & Lesbian Alliance Against Defamation's (GLAAD) Network Responsibility Index (NRI) released Wednesday. The cabler positively depicted the lives of gay, lesbian, bisexual and transgender characters in 55 percent of its original programming. Many of the shows, such as Pretty Little Liars and The Secret Life of the American Teenager, are aimed at a younger audience. ABC Family scored 37 percent last year.

Showtime also scored high marks with 37 percent, up from 32 percent last year. The pay cable network was helped by the premiere of Shameless and the second season of The Real L Word, an L Word reality series spinoff that revolves around the lives of a group of lesbians living in Los Angeles.

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 (ABC Family, A&E, AMC, FX, HBO, Showtime, Syfy, TBS, TNT and USA) for positive gay themes or characters aired between June 1, 2010 to May 31, 2011.

The CW led the networks for the second year in a row with 33 percent. Shows such as the nighttime teenage drama 90210 and American's Next Top Model helped the network win the top spot. The CW, Fox (29%) and ABC (23%) scored a “good” rating, while NBC (15%) and CBS (10%) were rated “adequate.”

NBC and CBS have struggled to diversify their programming. Both have previously been rated “failing” from GLAAD.

Following last year's report, in which CBS also scored lowest (7%) among all five networks, President Nina Tassler said she was “disappointed” in her network's track record and promised to do better.
