Mainstream is a term used to describe the dominant culture, ideas, and trends that are widely accepted by the majority of people. MEDIA and POP culture are two examples of mainstream culture. MEDIA refers to the various forms of communication, such as television, radio, newspapers, magazines, and the internet, which are used to disseminate information and entertainment. POP culture, on the other hand, is a term used to describe the popular culture of a particular time period, such as music, fashion, and art. Both MEDIA and POP culture are considered to be part of the mainstream culture.
