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.
In more recent years, following a more socially liberal perspective of sexuality, bisexuality has become more common in literature. This includes the work of Bret Easton Ellis, Anne Rice, Annie Proulx, and Alice Walker.
In 1981, X-men writer Chris Claremont intended the character Destiny to be the lover of Brotherhood of Mutants teammate Mystique, a shapeshifter, and had originally intended for Destiny and Mystique to be Nightcrawler's biological parents, with Mystique taking the form of a man for the conception. However, Marvel editors did not allow gay or bisexual characters at that time and the idea was abandoned.
British film Sunday Bloody Sunday (1971) portrayed a bisexual male named Bob with a lover of each gender. This was one of the earliest portrayals to be explicit on the subject of bisexuality, though film versions of several novels involving bisexuality, such as Women in Love (1969) and Goldfinger (1964) had been released earlier. The film is told from the perspectives of the homosexual partner and the heterosexual partner. Critics of the time described Bob as "shallow", "callous", and "selfish". Cite error: Invalid

In the early nineties, independent film Go Fish (1994), which portrays a lesbian love story, had a bisexual moment in which a lesbian-identified character has sex with a man and on her way home is challenged by a "jury," who question whether a woman who has sex with a man can call herself a lesbian. She contrasts how a gay man who has sex with a woman is characterized as being "bored, drunk [or] lonely" but if a lesbian has sex with a man "her whole life choice becomes suspect." In 1997, Kevin Smith's Chasing Amy took on the question of sexual identity in a story about a lesbian-identified woman who falls in love with a man, and ends with a straight-identified male beginning to question his attitudes and identity.

Torchwood is a spin-off of long running British sci-fi Doctor Who, created by Russell T Davies. The show is based in Cardiff, Wales, and deals with several LGBT themes, specifically bisexuality. 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
The lead male in the series, Captain Jack Harkness originated in parent series Doctor Who, which is considered a family show, as opposed to Torchwood's adult orienation. Davies has also described Jack as omnisexual.
