Youth subculture in the context of "Greaser (subculture)"

Youth culture refers to the societal norms of children, adolescents, and young adults. Specifically, it comprises the processes and symbolic systems that are shared by the youth and are distinct from those of adults in the community.

An emphasis on clothes, popular music, sports, vocabulary, and dating typically sets youth apart from other age groups. Within youth culture, there are many constantly changing youth subcultures, which may be divided based on race, ethnicity, economic status, public appearance, or a variety of other factors.

The Teddy Boys or Teds were a mainly British youth subculture originating in the early 1950s to mid-1960s and then revived in the 1970s who were interested in rock and roll and R&B music, wearing clothes partly inspired by the styles worn by dandies in the Edwardian period, which Savile Row tailors had attempted to re-introduce in Britain after the Second World War.

K-pop (Korean: 케이팝; RR: Keipap; an abbreviation of "Korean popular music") is a form of popular music originating in South Korea. The music genre that the term is used to refer to colloquially emerged in the 1990s as a form of youth subculture, with Korean musicians taking influence from Western dance music, hip-hop, R&B and rock. Today, K-pop commonly refers to the musical output of teen idol acts, chiefly girl groups and boy bands, who emphasize visual appeal and performance. As a pop genre, K-pop is characterized by its melodic quality and cultural hybridity.

K-pop can trace its origins to "rap dance", a fusion of hip-hop, techno and rock popularized by the group Seo Taiji and Boys, whose experimentation helped to modernize South Korea's contemporary music scene in the early 1990s. Their popularity with teenagers incentivized the music industry to focus on this demographic, with Lee Soo-man of SM Entertainment developing the Korean idol system in the late 1990s and creating acts like H.O.T. and S.E.S., which marked the "first generation" of K-pop. By the early 2000s, TVXQ and BoA achieved success in Japan and gained traction for the genre overseas.

Internet aesthetics are visual styles, subcultures, and thematic trends that originated or proliferated primarily through the Internet. Originally emerging out of the early online blogosphere among Millennials in the late 2000s and gaining significant cultural traction throughout the 2010s and 2020s amongst Gen Z. Internet aesthetics encompass a wide range of niche communities and visual identities associated with contemporary youth subcultures defined by their digital circulation, curated imagery, and symbolic references to technology, nostalgia, and alternative culture, typically blending elements of fashion, music, visual art, and memes.

These aesthetics were originally often associated with early blog-based platforms such as Tumblr. By the late 2010s to early 2020s, they evolved to encompass social media platforms like TikTok and Instagram, with the COVID-19 lockdowns being linked to the wider proliferation of these aesthetics online. Notable internet aesthetics include Seapunk, Vaporwave, Cottagecore, Goblincore, Gorpcore, E-girls and E-boys, Dark academia, and 2020 Alt.
