What is referred to as mainstream today was born from what was once considered underground. I believe this is a revolving cycle not just now in contemporary times but even in the past. Heller says that the mainstream takes the underground and call it cool. Which is to me a form of exploitation and in some case could be looked at as cultural appropriation. The merger between the two is a fine line, because sometimes it seems like the transition from underground to mainstreams feels seamless. The battle between the two can be very frustrating for creators themselves especially when business gets involved. As Heller said mass marketers steal ideals from visionaries and thens slightly change the idea or in some cases don’t change it at all, which is a very nasty practice but still occurs to this day.
