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.
