"Mainstream" refers to the ideas, attitudes, or activities that are widely accepted and practiced by the majority of people in a society. It often represents the dominant culture, which can influence trends in areas such as music, fashion, and media. For example, pop music is considered mainstream because it appeals to a large audience and is frequently played on popular radio stations. In contrast to niche or alternative movements, mainstream culture tends to prioritize accessibility and broad appeal. This can lead to the commercialization of certain trends, as seen in Hollywood films that aim to attract mass audiences. Overall, mainstream serves as a reflection of collective preferences and societal norms.
