The D-Generation was a popular and influential Australian TV sketch comedy show, produced and broadcast by the Australian Broadcasting Corporation (ABC) for two series, between 1986 and 1987. A further four specials were broadcast on the Seven Network between 1988 and 1989.

The series was produced and directed by Kris Noble and was created and written by a group of Melbourne University students who had gained local notoriety for their stage work: Rob Sitch, Santo Cilauro, Marg Downey, Michael Veitch, Magda Szubanski, John Harrison, and Tom Gleisner. Also part of the original team was Nick Bufalo, who appeared in the unscreened one-hour D-Generation pilot (1985), before accepting a long-running role on TV soap A Country Practice. Several of Bufalo's sketches from the pilot (including the famous Thunderbirds parody) were incorporated into series one, and Bufalo himself returned for the specials. Actress/comedian Jane Turner and New Zealander Tony Martin joined from series two, and Melbourne Uni Revue stars Mick Molloy and Jason Stephens were added for the specials.

Generation X, commonly abbreviated to Gen X, is the generation born after the Western post–World War II baby boom ended. While there is no universally agreed upon time frame, the term generally includes people born from the early 1960s through the early 1980s, usually no later than 1981 or 1982.

The term Generation X was coined by the Magnum photographer Robert Capa in the early 1950s. He would use it later as a title for a photo-essay about young men and women growing up immediately after the Second World War. The project first appeared in "Picture Post" (UK) and "Holiday" (US) in 1953. Describing his intention, Capa said 'We named this unknown generation, The Generation X, and even in our first enthusiasm we realised that we had something far bigger than our talents and pockets could cope with'. Author John Ulrich explains that, "Since then, "Generation X" has always signified a group of young people, seemingly without identity, who face an uncertain, ill-defined (and perhaps hostile) future. Subsequent appearances of the term in the mid-1960s and mid-1970s narrowed the referent for "Generation X" from Capa's global generation to specific sets of primarily white, male, working class British youth sub-cultures, from the spiffy mods and their rivals the rockers, to the more overtly negationist punk subculture,."

D Generation (also known as DGen) are an American glam punk band formed in 1991 in New York City. The band broke up in 1999, but will reunite in 2011 for shows. During its history the band released three albums, to much critical acclaim. The group's sound blurred the lines between punk rock, glam rock and garage rock.

The original line-up for D Generation consisted of vocalist Jesse Malin (who had previously played with New York band Heart Attack during the late 1980s), guitarists Danny Sage (also an ex-Heart Attack member) and Richard Bacchus, John Carco on bass, Howie Pyro on guitar, and drummer Michael Wildwood. The band had not yet been named, although much of the material would later be performed and recorded by D Generation. The line up did not last. After bassist John Carco quit (later to join forces with Dee Dee Ramone), Malin and Pyro (who had switched to bass) continued to play, naming the band, and Sage and Wildwood left briefly to finish up their previous projects and were replaced for a brief time by Georgie Seville and Belvy K respectively. Sage and Wildwood soon returned, and this is the line-up D Generation is best known for.^{[citation needed]}
