Indie music has significantly impacted and innovated the entertainment industry over time. It began with innovators in the 1950s-1960s, grew with early adopters in the late 1960s-1970s, became mainstream with the early majority in the 1980s, and was nearly ubiquitous with the late majority by the 1990s. Today, indie influences have spread far beyond just music into other creative industries and subcultures. Indie music has demonstrated attributes of an innovation by having relative advantage over major labels, compatibility, trialability, and increasing observability over decades as it diffused through society.
