( CNN ) -- Although the general public may be embracing the LGBT community more these days , it does n't look like Hollywood is keeping up . That 's the message of GLAAD 's 2014 Studio Responsibility Index , which charts the `` quantity , quality and diversity of images of LGBT people in films released by the seven largest motion picture studios during the 2013 calendar year . '' This year 's study found that of the 102 films released by the major studios in 2013 , only 17 included characters identified as lesbian , gay or bisexual . And of those 17 , the study concluded , most were minor characters , some of which GLAAD characterized as `` defamatory representations . '' `` The lack of substantial LGBT characters in mainstream film , in addition to the outdated humor and stereotypes , suggests large Hollywood studios may be doing more harm than good when it comes to worldwide understanding of the LGBT community , '' GLAAD CEO and President Sarah Kate Ellis said in a statement . `` These studios have the eyes and ears of millions of audience members , and should reflect the true fabric of our society rather than feed into the hatred and prejudice against LGBT people too often seen around the globe . '' 20th Century Fox , Lionsgate , Universal Pictures and Walt Disney Studios were graded as `` adequate '' for their portrayal of the community , while both Warner Bros. and Paramount were rated as `` failing '' for `` including only minor and offensive portrayals of LGBT . '' Warner Bros. is owned by the parent company of CNN . Sony Pictures was the only studio to receive a `` good '' score for having several LGBT-inclusive films , including `` Mortal Instruments : City of Bones . '' Two films , `` Riddick '' and `` Pain and Gain , '' were singled out for having offensive portrayals . Films were judged by the the organization 's `` Vito Russo Test , '' named after the film historian and GLAAD co-founder . In order to pass the test , a film had to meet the following criteria : . â€¢ The film must contain a character that is identifiably lesbian , gay , bisexual and/or transgender . â€¢ That character must not be solely or predominantly defined by their sexual orientation or gender identity . i.e . They are made up of the same sort of unique character traits commonly used to differentiate straight characters from one another . â€¢ The LGBT character must be tied into the plot in such a way that their removal would have a significant effect . They are not there to simply provide colorful commentary , paint urban authenticity or ( perhaps most commonly ) set up a punchline . The character should `` matter . '' Of the 17 films with LGBT characters , only seven passed the Vito Russo Test . The study also notes that unlike films , `` TV seems to have entered another golden age , where the programming is not only incredibly thematically diverse ( and prolific ) , but is also fertile ground for creators to tell truly unique and innovative stories . Not by accident , it 's also the best place in popular culture to find complex and resonant representations of LGBT people that connect with a mainstream audience .

GLAAD found that fewer than 20 % of last year 's films had LGBT characters . Two films were cited for having offensive portrayals . The first was the movie " Straight Outta Compton " which featured a gay character, but it didn't have any scenes with him in them.
