GLAAD

http://www.glaad.org
 GLAAD is the Gay and Lesbian association against Defamation. It was founded in 1985 as a media advocacy organisation originally created in order to combat the homophobic presentation of the HIV/AIDs aids epidemic in the New York Post and other publications at this time. The association now works to challenge companies and businesses that discriminate against individuals who are not straight or cis-gendered.
They work within the news and entertainment industries to help the visibility of the LGBT community. It is important to have this as these minorities are not often shown in the mainstream media, and if they are it they are often portrayed with a negative or mocking attitude.
GLAAD also uses social media to push for marriage reform and works within faith groups for LGBT acceptance in the USA.
