The portrayal of bisexuality in the media reflects societal attitudes towards bisexuality.
Virginia Woolf's Orlando: A Biography (1928) is one of the earliest examples of bisexuality in literature. The story about a man who changes into a woman without a second thought was based on the life of Woolf's then lover Vita Sackville-West, a bisexual like Woolf herself. Woolf's used the gender switch to avoid the book being banned for homosexual content, and was successful for it. Following Sackille-West's death, her son Nigel Nicolson would publish Portrait of a Marriage, one of her diaries recounting her affair with a woman during her marriage to Harold Nicolson. Other early, subtle examples include works of D.H. Lawrence, such as Women in Love (1920), and Colette's Claudine (1900-1903) series.

Each of the main characters in Torchwood has same-sex encounters at some point in the first season, with The Sun describing all of the characters on Torchwood as bisexual. Davies has said that he hopes to defy audience expectations of monosexual characters:
"Without making it political or dull, this is going to be a very bisexual programme. I want to knock down the barriers so we can't define which of the characters is gay. We need to start mixing things up, rather than thinking, 'This is a gay character and he'll only ever go off with men.'" - Russel T. Davies
