True Blood is the most gay-friendly scripted program on television, a new Gay & Lesbian Alliance Against Defamation (GLAAD) report says.

The 15th annual “Where We Are On TV” report released Tuesday found that the HBO vampire drama included the most gay characters on television.

“Thanks to its large cast, HBO's True Blood is the most inclusive program currently on television, featuring six regular and recurring LGBT (lesbian, gay, bisexual and transgender) characters,” the survey says.

Overall, the 2010-2011 network season has 23 LGBT primetime characters, five more than last year. Cablers have added gay characters at a faster pace this year. After declining to a low of 25 characters last year, cable networks rebounded to 35 in the upcoming season. But that's a lower number than in 2007, when cablers regularly featured 40 gay characters during primetime.

Among the networks, ABC again topped the list with 11 gay characters out of 152 (7.2%), followed by Fox with 5 (5%), CW with 3 (4.5%), and NBC with 3 (2.1%). CBS, which has previously promised to increase its diversity, came in last with 1 (0.8%).

“The increase in lesbian, gay and bisexual characters on primetime television not only reflects the shift in American culture towards greater awareness and understanding of our community, but also a new industry standard that a growing number of creators and networks are adopting,” Jarrett Barrios, president of GLAAD, said. “The recent critical and commercial success of shows like Modern Family and Glee clearly indicate that mainstream audiences embrace gay characters and want to see well-crafted stories about our lives.”
