NEW YORK — The number of gay and bisexual characters on scripted broadcast network TV is at its highest-ever level in the season ahead, according to the Gay & Lesbian Alliance Against Defamation. The total on cable television is also going up.

The 17th annual "Where We Are on TV" report, released Friday, found that 4.4 percent of actors appearing regularly on prime-time network drama and comedy series during the 2012-13 season will portray lesbian, gay, bisexual or transgender characters. That is up from 2.9 percent in 2011, which saw a dip in what had been a growing annual trend.

The study reviewed 97 scripted TV programs scheduled to air in the upcoming season on the broadcast networks, counting a total of 701 series regular characters. The study found that 31 of them are LGBT characters.

ABC has the highest amount, with 10 out of 194, or 5.2 percent, of their regular characters identified as LGBT.

After leading last year, Fox ranks second with six LGBT characters out of 118 total series regulars, or 5.1 percent.

CBS was saluted as much improved, with four out of 142 LGBT series regulars, or 2.8 percent, up from 0.7 percent last year. Among CBS's new fall series is "Partners," a comedy about two childhood friends and business partners, one of whom is gay and in a relationship. The network's lineup represents "an authentic and conscious effort by CBS to improve its diversity," the study said.

Regular gay and lesbian characters on what the study termed "mainstream" cable television has also risen this season to 35, up from 29 last season.

Among those networks, Showtime leads with 12 LGBT characters. The study also cited HBO, FX, Adult Swim, ABC Family, MTV, Syfy and TeenNick.

The HBO drama "True Blood" remains cable's most inclusive series, featuring six LGBT characters.

On broadcast TV, male characters (64 percent) continue to outweigh female characters (36 percent, including the transgender character Unique on "Glee").

Compared with last year, African-American representation has grown from 9.9 percent to 12 percent, while Hispanic representation has decreased from 5.6 percent to 4.1 percent.

"It is vital for networks to weave complex and diverse story lines of LGBT people in the different programs they air," said GLAAD President Herndon Graddick. "More and more Americans have come to accept their LGBT family members, friends, co-workers and peers, and as audiences tune into their favorite programs, they expect to see the same diversity of people they encounter in their daily lives."

  • Kurt and Blaine, "Glee"

    Kurt Hummel (Chris Colfer) and Blaine Anderson ((Darren Criss) were the epitome of high school sweethearts on Fox's "Glee" -- and the fan-favorite couple among most Gleeks. Klaine is kind of like a holy word in the "Glee" Bible. Not only were they each other's first boyfriends, but they lost their virginity to each other during the controversial Season 3 episode, "First Time." Blaine has also helped Kurt through some tough times, including standing up to Kurt's bully, Dave Karofsky, and taking a laced slushy to the eye to protect him. Though Kurt's move to New York led to some major problems for the couple, we still have faith that they'll end up together.

  • Michael and Ben, "Queer As Folk"

    For the first two seasons of "Queer As Folk," we thought that Michael Novotny (Hal Sparks) would never get past his obsession with his best friend Brian Kinney (Gale Harold) -- but then he met writer and fellow comic book lover Ben Bruckner (Robert Gant) and his love life took a turn for the better. Together, Michael and Ben had to deal with Ben's steroid use and his HIV, but eventually the two celebrated their marriage in Canada, with Brian by Michael's side, and they eventually had two children. Sure, Ben might think they're "conformist homosexuals," but we're just happy Michael finally got the happy ending that he deserved. They may not have been the show's most popular couple, but they were the cutest. (Sorry, Brian and Justin fans!)

  • David and Keith, "Six Feet Under"

    There was just something that felt authentic and real about David (Michael C. Hall) and Keith's (Mathew St. Patrick) relationship on "Six Feet Under." Keith supported David as he came to terms with his sexuality, came out to his family and struggled to recover from a traumatic kidnapping. They had their struggles, but eventually settled down together, adopted two kids and, as the series finale's flashforward showed, lived a nice long life and eventually got legally married in the state of California. (Yep, creator Alan Ball predicted the Prop 8 ruling way back in 2005!)

  • Cam & Mitchell, "Modern Family"

    Arguably the most popular gay couple on television at the moment, Cam (Eric Stonestreet) and Mitchell (Jesse Tyler Ferguson) are the perfect complement to one another. Mitchell's serious and more introverted, and Cam is a jovial clown (occasionally even literally -- we love Fizbo!). Always a blast to watch, the couple's antics are both heartwarming and hilarious. Even if we don't get to see them be affectionate with each other nearly often enough, we love seeing them raise their adopted daughter Lily together. "Modern Family" writers, now it's time to get these two properly (and legally) hitched!

  • Jack McPhee & Doug Witter, "Dawson's Creek"

    There were many hearts broken in the "Creek," but it was most difficult to watch Jack (Kerr Smith) struggle with each of his relationships after he came out of the closet. When he finally hooked up with Pacey's brother Doug (Dylan Neal), we couldn't help but cheer, and Doug's hesitation to come out at work made Jack finally step up as a confident and proud gay man. Their story wrapped on a bittersweet note in the series finale, as they agreed to raise dying Jen's (Michelle Williams) daughter Amy together in Capeside.

  • Callie and Arizona, "Grey's Anatomy"

    Callie (Sara Ramirez) tried being married to a man (R.I.P. George O'Malley) before realizing she had feelings for women. Her first try at having a girlfriend (Erica Hahn, played by Brooke Smith) didn't end well, but her rebound relationship with Arizona (Jessica Capshaw) made her embrace her sexuality, even if her religious father couldn't. Their relationship has survived quite a bit -- including the loss of Arizona's leg (as a result of Callie's decision) -- but the two vowed to stay together since getting married in front of all their friends, with Dr. Miranda Bailey (Chandra Wilson) officiating. Even with the madness at Seattle Grace, they're still holding on.

  • Willow and Tara, "Buffy the Vampire Slayer"

    You can just call Willow (Alyson Hannigan) and Tara (Amber Benson) the Wiccans that stole our hearts. From their budding romance that grew along with their powers to the tragic end, Willow and Tara were the couple we loved to love. If Tara was under Willow's spell (yes, we're referencing Tara's song in "Once More With Feeling" and the fact that Willow really did cast spells on Tara, grrr), then we were under theirs.

  • Barca and Pietros, "Spartacus: Blood and Sand"

    Two of this show's most winning qualities are the fact that that it depicts a whole range of sexuality with clear-eyed thoughtfulness and that gay relationships aren't treated any differently than heterosexual ones. Barca (Antonio Te Maioho) was one of the fiercest gladiators in "Spartacus: Blood and Sand," and at the end of a long day in the arena, this tough warrior found comfort in the arms of a young man named Pietros (Eka Darville). The couple had their share of ups and downs, but Barca's intimacy with Pietros gave dimension and depth to the character. Terrible things tend to happen to the "Sparatacus" gladiators, who are slaves after all, but at least we got to see the sweet sides of two men who didn't often have occasion to let down their guards.

  • Bette and Tina, "The L Word"

    For six seasons, fans of Showtime's groundbreaking lesbian-centric series "The L Word" followed the highs and lows of Bette (Jennifer Beals) and Tina's (Laurel Holloman) complicated relationship. There was adultery and pregnancy struggles and tons of emotion that all culminated in that very absurd murder in the series finale. Still, we'd like to think that Tibette stayed together ... even in the Jenny Schecter aftermath.

  • Kevin and Scotty, "Brothers and Sisters"

    Kevin (Matthew Rhys) and Scotty (Luke Macfarlane) had their rough patches, but Scotty was the only man who could put up with Kevin's neuroses and the Walker family drama. Their commitment ceremony in Season 2 -- the first same-sex TV marriage ever to involve main characters -- didn't make life a total fairytale, but they did weather quite a few more storms (cheating and a failed surrogacy among them) before adopting daughter Olivia.

  • Emily and Maya, "Pretty Little Liars"

    It was hardly an easy road for formerly closeted lesbian Emily (Shay Mitchell) on ABC Family's "Pretty Little Liars." But when she met Maya (Bianca Lawson), the new girl living in her missing BFF's house (yep, you read that right), she was smitten. Though Emily's mom tried to keep them apart and Maya's parents sent her to boot camp, the two finally found their way back to each other. Maya even made a grand gesture and professed her love to Emily. Sadly, Maya was murdered and Emily, in turn, murdered her killer. Not that we'd condone that but still ... it's sweet as far was "Pretty Little Liars" goes.
