In addition, GLAAD found that 3.9 percent of series regulars on prime-time broadcast scripted series are lesbian, gay or bisexual (up from 3.3 percent last year). Fox has the highest percentage, with 6.5 percent of series regulars being lesbian, gay or bisexual. The CW has no regular LGBT characters on any of its shows.

Thirty-three recurring characters on broadcast prime-time shows are lesbian, gay or bisexual, though none are transgender. On scripted cable series, 64 regular characters and 41 recurring characters are LGBT.

Going forward, networks will need to increase their representation of transgender characters in order to receive an Excellent rating from GLAAD, the organization said.

"Television networks are playing a key role in promoting cultural understanding of LGBT lives around the world, and are now producing some of the best LGBT-inclusive programming we've yet seen," said GLAAD President and CEO Sarah Kate Ellis said in a statement. "As they move forward with new programs and story lines, networks must also keep an eye towards diversity and strive to include significant transgender content comparable to those efforts being made by their online competitors, such as Netflix'sOrange is the New Black and Amazon's Transparent."
