I'm not saying the term means this, I'm pointing out why its important because the industry is global.
As in, a show that shows many different demographics in America, would make sense because the actors in those shows can capture an audiences in other countries, on top of how America is as a melting pot, having many different demographics shows culturally how the country is, this is also allows even Americans that might share this demographic to be connected to the story on a deeper level of they can understand the character, like if a show is about a second generation Korean in America, not only can people who share this understand the show on a deeper level, but the market in Korea can understand it as well, either knowing family members that did this or imagining if they did it themselves
So my point is not saying the term means this, its saying the concept of inclusion makes a lot of sense in American art forms cause we are a melting pot in the first place, but also that a global market that exist can also gravitate towards the show.
Look at the Walking Dead's Steven Yeun. So inclusion makes sense cause clearly this comic and show is based in America, which means it would not be odd to find any different demographics.
lol, a random image of a crowd in America...
Now, here is Steven in a Korean film I seen a few years back.
Now consider, the show Walking Dead is about a zombie apocalypse in America, has inclusion as clearly, its happening in America. This demographic can understand his character a great deal if they live in America, BUT overseas the show can capture appeal as well, as clearly this has made him popular to the point of being in other films in Korea.
