In the early 1970s, a group of record dealers in the United States began inventing names for obscure vinyl records to make them more valuable to collectors. They called these newly minted categories Northern soul and garage punk, terms that did not exist when the music was originally recorded. These labels were retroactive inventions, applied years after the fact to create a sense of history and scarcity where none had existed. The process was so effective that it turned a few forgotten singles into cultural artifacts worth thousands of dollars. Music journalist Simon Reynolds later described this phenomenon as genre-as-retroactive-fiction, noting that the labels were often pushed by dealers to increase the monetary value of the original records. This practice established a pattern where the definition of a genre could be manufactured by those who controlled the market, rather than emerging organically from the artists themselves. The term microgenre itself appeared in a 1975 French article about historical fiction, defining it as a narrowly defined group of texts connected in time and space, but its true power lay in the music industry's ability to commodify obscurity. By the 1980s, the label freakbeat was coined by Phil Smee, and sunshine pop emerged in the 1990s, continuing the tradition of creating new categories to describe existing sounds. Even Robert Christgau, a prominent music critic, coined the term pigfuck in the early 1980s to describe the music of Sonic Youth, a term that later took on a life of its own to denote a specific style of noise rock music. These early examples proved that a genre could be invented, marketed, and accepted as real, setting the stage for the digital explosion that would follow decades later.
The Blogosphere Explosion
By 2009, the creation of musical microgenres had shifted from the physical record bins of collectors to the digital pages of online blogs. The speed at which these new categories achieved recognition accelerated substantially, driven by software advances, faster internet connections, and the globalized proliferation of music. In that year, a writer for the New York Times observed that indie rock was evolving into an ever-expanding, incomprehensibly cluttered taxonomy of subgenres. The term chillwave was coined by the ironic music blog Hipster Runoff around 2009 as an internet meme, marking one of the first music genres to develop primarily online. The term did not gain mainstream currency until early 2010, when it was the subject of articles by the Wall Street Journal and the New York Times. Journalist Emilie Friedlander later wrote in 2019 that chillwave was the internet electronic micro-genre that launched a hundred internet electronic micro-genres, including vaporwave, witch house, seapunk, and shitgaze. These genres were often described as music scenes created out of thin air, existing as much in the minds of writers and listeners as they did in the recordings themselves. Pitchfork's Jonny Coleman noted that the line between a real genre that sounds fake and a fake genre that could be real was as thin as ever, if it existed at all. This era saw the rise of bloghouse, blog rap, and blog rock, all of which predated the chillwave phenomenon but shared its reliance on online communities to define and spread their existence. The internet allowed for the rapid dissemination of these labels, turning niche interests into global movements in a matter of months.
