Disco is the 1970s music genre that everyone loves to hate (YMMV, though).
Originating in France ("disco" is short for "discotheque") in the years during and after World War II, discotheques were a response to the straitened times that made it difficult (and even dangerous, during the Nazi occupation) to offer live music and floor shows. Similar in concept to the "Juke Joints" of the 1930s only using Disk Jockeys instead of Juke boxes, discos were a new form of night club based around recorded music and a dance floor that turned their patrons into the floor show in a form of kinetic karaoke. While eliminating bands and floor shows greatly simplified the logistics of operating a night club, discos also offered the added advantage that one could simply ditch the turntable and run if one came to the negative attention of the local authorities. Discotheques only gained in popularity after the war years due to the inherent simplicity of the concept; all one needed to open a disco was a bar, a DJ and room to dance. (Standard Disco Equipment came later.) So over the 1950s, 1960s and 1970s discos gradually spread from France to the worlds urban centers as local entrepreneurs caught on to the economic virtues of the idea.
But in the early 1970s the prevailing tides of pop music shifted in a direction that wasn't particularly danceable. Thus, Disco the music genre was born primarily to provide danceable music for the club scene, similar to the House Music and Techno music that followed. As a genre, the music itself was fairly basic: A fusion of Funk and pop styles with simple hooks and lots of rhythm tracks layered over a driving beat that took full advantage of the newly-popular synthesizers ability to produce cadenced notes with the press of a single key. For a brief time in the late 1970s, disco was the biggest thing ever, spurred on by the blockbuster success of the film Saturday Night Fever and its soundtrack. Discotheques like New York's famous Studio 54 became the places for the hip and trendy to be and be seen.
Then, even before 1980s officially started, a backlash emerged. Disco's hip and urban image had little appeal to people who were neither while many fans of white pop and black funk hated disco's fusion of their preferred styles. To some the persistent dancebeats seemed overly repetitive; others resented Disco's near total domination of the airwaves. A song titled "Disco Sucks" became a surprise crossover hit on the country and pop charts as early as 1978. Radio stations started advertising "Bee Gees free weekends." The Chicago White Sox hosted a "Disco Demolition Night" promotion that got so out of hand it turned into a riot. It got so bad that even rock artists who were influenced by disco, like Rod Stewart, were attacked and parodied.
Attacked on all sides and with a powerful image against it, disco was fading fast and completely dead by early 1981, and with it the fashions and styles related to or heavily associated with it (such as flared trousers). For the rest of 1980s, admitting that you liked disco may as well have been admitting to cannibalism. While dance artists like Madonna and Janet Jackson continued to take influence from it and it also had an influence on early Hip-Hop, whatever remaining fandom the genre itself still had was restricted to gay clubs, which marginalized it even further. Disco would start to reemerge (or at least, come to the surface for fresh air) during 1990s' wave of nostalgia for the 1970s and its backlash against all things 1980s, mainly in the form of sampling for rap and dance songs (it didn't hurt that most popular dance music, particularly House and its offshoots, can trace its lineage straight back to disco). Still, during this same time, The Simpsons had a character named Disco Stu who was used almost purely for comic relief, showing that the genre was still a ways away from returning to public acceptance.
Today, it seems as though the Trope Namer for Deader Than Disco is becoming a subversion of its own trope. The newest generation of teenagers has grown up with no memory of disco or their parents' hatred of it; to them it's simply a style of music that they will like or dislike on their own merits. The Sirius XM disco station probably introduced more than a few new fans, as seen by the surprisingly large reaction to its removal, which forced it to be Un-Canceled. Similarly, the advent of the internet allowed some people to discover disco for the first time after terrestrial radio stations stopped playing it. Finally, music historians who have investigated why disco became so fiercely hated agree that much of the backlash was due not to overexposure but to homophobia and, to a lesser degree, sexism and racism (disco having succeeded, if only for a brief time, in uniting Americans across color and sexual lines - being an African American music genre that had heavy female participation). While few new disco songs are being recorded, many of the negative connotations associated with it have died out, and many of its enemies have toned down the vitriol.
Of course, the above only describes the United States. If you ask a Brit or a European about any anti-disco backlash, you will likely get a series of puzzled looks. Across The Pond, post-disco stayed popular well into the '80s, heavily influencing New Wave Music, Synth-Pop and other styles of popular music such as Italo Disco, and in Russia, it lingered well into early 1990s. For much of The Eighties, the global pop charts were dominated by derivatives of disco, post-disco and Punk Rock. Artists like Amanda Wilson and Laura White now carry its torch proudly into the present day. And this isn't even taking into account disco's influence on underground music, especially Post-Punk bands like Public Image Ltd. and ex-No Wavers like Material, Contortions and Liquid Liquid. All operated under the basic premise of "take a disco beat and pile weird stuff on top of it", often to great and innovative effect. PiL even had a hit with a song called "Death Disco"... although who was singing probably had some effect. There was also the Industrial fascination with Eurodisco, but that's another matter entirely. This marriage of Punk and Disco later evolved into the Alternative Dance genre of the late 1980s and early 1990s and the more overtly disco-influenced Dance-Punk genre of the early 2000s
Things you're likely to see in a depiction of a disco include:
- A disco ball is pretty much a given. Fun fact
- An awesome sound system. More modern takes will usually feature a DJ station with turntables and mixers.
- A stage, if a band is performing.
- A central dance floor where the characters can bust some cool moves.
- A fancy light show, including some combination of the following: Lots of blinking colored lights; plain lights hung from the ceiling; floor panels that change color; UV, neon, and/or LED lights and signs.
- Pyrotechnics and other cool effects, such as lasers, a smoke machine, bubbles, confetti, or fake snow
- A bar
- The "Staying Alive" dance
Tropes inspired by Disco:
Groups and musicians associated with Disco:
- The Bee Gees
- Blondie's biggest hits "Heart of Glass" and "Call Me" were in this style, although both were a case of Genre Adultery and Black Sheep Hit
- Boney M.
- David Bowie (Inadvertently: Young Americans and Station to Station, his 1975 and '76 forays into soul/funk, did well with the disco crowd — but he was not a fan of this genre, and 1979's "D.J." is in part a mockery of the subculture. That said, he didn't hold it against Moroder [he worked with him on the theme song from the 1982 Cat People remake] or Chic's Nile Rodgers, whom he hired to produce his 1983 album Let's Dance, a mainstream pop-rock effort.)
- Tina Charles
- Leif Garrett
- Earth, Wind & Fire
- Isaac Hayes (mid-1970s onward)
- The Jackson Five: They moved into this direction from the mid 1970s on.

Media representative or depicting the Disco Era:

- On a side note, language textbooks frequently apppear horrifically outdated because they always seem to have at least one reference to someone asking for the direction to the discotheque. However, note that "discothèque" is itself a French word imported into English. In Europe. Some form of the word is generally used as the term for a nightclub with bright lights and music to dance to, what we in the states generally just call a club.
