There was virtually no appreciation for the imperfections of lo-fi music among critics until the 1980s, during which there was an emergent romanticism for home-recording and "do-it-yourself" (DIY) qualities.[9] Afterward, "DIY" was often used interchangeably with "lo-fi".[10] By the end of the 1980s, qualities such as "home-recorded", "technically primitive", and "inexpensive equipment" were commonly associated with the "lo-fi" label, and throughout the 1990s, such ideas became central to how "lo-fi" was popularly understood.[11] Consequently, in 2003, the Oxford Dictionary added a second definition for the term—"a genre of rock music characterized by minimal production, giving a raw and unsophisticated sound".
