Network television is doing a better job at reflecting the lives of gay and bisexual characters, a new Gay & Lesbian Alliance Against Defamation report says.

The 14th annual “Where We Are on TV” report released Wednesday found a slight increase in the number of gay and lesbian characters on network primetime schedules.

Overall, the 2009-2010 network season has 18 LGBT characters, two more than last year, while cable watchers are getting fewer gay characters. The number of characters on mainstream cable television has plummeted to 25, or a 38% decline in two years.

Among the networks, ABC again topped the list with 8 gay characters out of 168 (5%), followed by Fox with 4 (4%), NBC with 3 (3%), and the CW with 2 (3%). CBS, which has previously promised to increase its diversity, came in last with none.

The group said it was pleased with the increasing appearance of non-stereotypical gay characters on network television.

“It is promising to see not only an increase in the quality of lesbian, gay, bisexual and transgender television characters but that storylines about the LGBT community are becoming more reflective of current issues impacting our lives,” said GLAAD president Jarrett Barrios in a statement.

“Americans now have the opportunity to see LGBT couples marrying on shows like Brothers & Sisters, raising children on Modern Family and LGBT youth coming out on Glee. As more and more Americans see fair and accurate images of our community and the issues impacting our lives reflected on the small screen, they come to accept and better understand their LGBT family members and neighbors,” he added.
