U.K. public broadcaster the BBC should be bolder and more creative with its depiction of lesbian, gay and bisexual people who are still sidelined and stereotyped on television, says a new report commissioned by the BBC itself. According to the report, lesbian, gay and bisexual (LGB) people were "still relatively invisible" across all media, "especially lesbian women and bisexual people." The groups' depiction in the media "still needs to reflect the diversity of LGB people and to avoid stereotypes. The report, after two years of research, concludes that the BBC should feature more lesbian, gay and bisexual people across its bouquet of channels and programming. It also called for the BBC to put LGB folks on children's shows and sport, and to cover LGB issues on BBC News in a more nuanced fashion. The investigation into the media portrayal of LGB audiences consisted of interviews with LGB organizations and reps and comes two years after a 2010 study carried out by the BBC. In two parts, the updated research also features the views of around 3,500 people on the BBC's own independently run audience reaction panel, Pulse. The BBC's acting director general Tim Davie, chairman of the BBC working group which commissioned the review, said: "The BBC has a fundamental obligation to serve all its audiences. In fact, it's one of the BBC's public purposes to reflect the diversity of UK life.
