Dance-pop is a pop and dance subgenre that originated in the early 1980s. It is generally up-tempo music intended for nightclubs with the intention of being danceable but also suitable for contemporary hit radio. Developing from a combination of electronic dance music and pop music, with influences of disco  , post-disco and synth-pop,  it is generally characterised by strong beats with easy, uncomplicated song structures  which are generally more similar to pop music than the more free-form dance genre, with an emphasis on melody as well as catchy tunes.  The genre, on the whole, tends to be producer-driven, despite some notable exceptions. 
Dance-pop borrowed influences from other genres, which varied by producer, artist and period. Such include contemporary R&B, house, trance, techno, new jack swing, funk, synthpop, electropop and some forms of europop.
Dance-pop is a popular mainstream style of music and there have been numerous pop artists and groups who perform in the genre. Notable ones include Madonna, Britney Spears, Kylie Minogue, Gloria Estefan, Christina Aguilera, Jennifer Lopez, Spice Girls, Paula Abdul, Backstreet Boys, Michael Jackson, NSYNC, Destiny's Child, Janet Jackson, Rihanna, Miley Cyrus, Katy Perry, Lady Gaga, Ariana Grande and Selena Gomez.
As the term "disco" started to go out of fashion by the late 1970s to early 1980s, other terms were commonly used to describe disco-based music, such as "post-disco", "club", "dance" or "dance-pop" music.  These genres were, in essence, a more modern variant of disco music known as post-disco, which tended to be more experimental, electronic and producer / DJ -driven, often using sequencers and synthesizers.
Dance-pop music emerged in the 1980s as a combination of dance and pop, or post-disco, which was up-tempo and simple, club-natured, producer-driven and catchy. Dance-pop was more up-tempo and dancey than regular pop, yet more structured and less free-form than dance music, usually combining pop's easy structure and catchy tunes with dance's strong beat and up-tempo nature. Dance-pop music was usually created, composed and produced by record producers who would then hire singers to perform the songs.
In the beginning of the 80s disco was an anathema to the mainstream pop. According to prominent Allmusic critic Stephen Thomas Erlewine, Madonna had a huge role in popularizing dance music as mainstream music, utilizing her charisma, chutzpah and sex appeal. Erlewine claimed that Madonna "launched dance-pop" and set the standard for the genre for the next two decades. As the primary songwriter on her self-titled debut album and a co-producer by her third record, Madonna's insistence on being involved in all creative aspects of her work was highly unusual for a female dance-pop vocalist at the time. The staff of Vice magazine stated that her debut album "drew the blueprint for future dance-pop."
In the 1980s dance-pop was closely aligned to other up-tempo electronic genres, such as Hi-NRG. Prominent producers in the 1980s included Stock, Aitken and Waterman, who created Hi-NRG/dance-pop for artists such as Kylie Minogue, Dead or Alive and Bananarama. During the decade, dance-pop borrowed influences from funk (e.g. Michael Jackson and Whitney Houston), new jack swing (e.g. Janet Jackson and Paula Abdul), and contemporary R&B.
By the 1990s, dance-pop had become a major genre in popular music. Several dance-pop groups and artists emerged during the 1990s, such as the Spice Girls, Britney Spears, Christina Aguilera, Jessica Simpson, Backstreet Boys, and 'NSYNC. During the early 1990s, dance-pop borrowed influences from house music (e.g. Right Said Fred's " I'm Too Sexy ", Taylor Dayne's Soul Dancing , and Madonna's " Vogue ", " Rescue Me " and " Deeper and Deeper "), as well as contemporary R&B and new jack swing (e.g. Shanice's " I Love Your Smile ").
By the late 1990s, electronic influences became evident in dance-pop music; Madonna's critically acclaimed and commercially successful album Ray of Light (1998) incorporated techno, trance and other forms of electronic dance music, bringing electronica into mainstream dance-pop. Additionally, also in 1998, Cher released a dance-pop song called " Believe " which made usage of a technological innovation of the time, Auto-Tune. An audio processor and a form of pitch modification software, Auto-Tune is commonly used as a way to correct pitch and to create special effects. Since the late 1990s, the use of Auto-Tune processing has become a common feature of dance-pop music.
At the beginning of the 2000s, dance-pop music was still prominent, and highly electronic in style, influenced by genres such as trance, house, techno and electro. Nonetheless, as R&B and hip hop became extremely popular from the early part of the decade onwards, dance-pop often borrowed a lot of its influences from urban music. Dance-pop stars from the 1980s and 1990s such as Britney Spears, Christina Aguilera, Madonna, Janet Jackson and Kylie Minogue continued to achieve success at the beginning of the decade. Whilst a lot of dance-pop at the time was R&B-influenced, many records started to return to their disco roots; Kylie Minogue's albums such as Light Years (2000) and Fever (2001) contained influences of disco music, or a new 21st-century version of the genre known as Nu-disco ; hit singles such as " Spinning Around " (2000) and " Can't Get You Out of My Head " (2001) also contained disco traces.  In Madonna's case, her album Music (2000) contained elements of Euro disco, especially the successful eponymous lead single.
Nevertheless, it was not until the mid-to-latter part of the decade when dance-pop music returned greatly to its disco roots; this can be seen with Madonna's album Confessions on a Dance Floor (2005), which borrowed strong influences from the genre, especially from 1970s artists and bands such as ABBA, Giorgio Moroder, the Bee Gees and Donna Summer. Britney Spears' album Blackout (2007) contained influences of Euro disco.
The mid-to-late 2000s saw the arrival of several new dance-pop artists, including Rihanna, Kesha, Lady Gaga and Katy Perry. This period in time also saw dance-pop's return to its more electronic roots aside from its disco ones, with strong influences of synthpop and electropop ; Rihanna's singles in the dance-pop genre, including " Don't Stop the Music " and " Disturbia ", contained electronic influences, the former of which has elements of house music,  the latter electropop; Lady Gaga's singles " Just Dance " and " Poker Face " were also heavily influenced by synthpop and electropop; Kesha's debut single, " Tik Tok ", was also highly electronic in style and employed a video game beat. Katy Perry's " Hot N Cold " (2008), " California Gurls " (2010), and " Firework " (2010), which were major commercial hits, also showcased influences of electropop and house music.
The 2010s so far have, similarly to the late 2000s, seen strong electronic influences present within dance-pop and also heavy emphasis on bass-heavy drum beats. Dance-pop artists such as Britney Spears, Lady Gaga, Katy Perry, Madonna, Kesha, Christina Aguilera, Usher, and Rihanna remain very popular, and several new recording artists within the genre have or are starting to emerge. Country-pop artist Taylor Swift's albums Red (2012) and 1989 (2014) both contain more of a pop-influenced sound which features production by dance-pop producers Max Martin and Shellback. Ariana Grande's single " Problem " was a big hit in 2014.
