Although "lo-fi" has been in the cultural lexicon for approximately as long as "high fidelity", WFMU DJ William Berger is usually credited with popularizing the term in 1986. At various points since the 1980s, "lo-fi" has been connected with cassette culture, the DIY ethos of punk, primitivism, outsider music, authenticity, slacker/Generation X stereotypes, and cultural nostalgia. The notion of "bedroom" musicians expanded following the rise of modern digital audio workstations, and in the late 2000s, lo-fi aesthetics served as the basis of the chillwave and hypnagogic pop music genres.[3]
