It's a bit of both. The media displays a wide variety of content, and the audience decides what to consume and what to leave aside. While the society consumes the content that displays certain image of beauty, the media sends more images including the most consumed beauty standards, so as to keep the consumers and gain even more audience. As a conclusion, the media displays what the society wants to consume.
Definitely both, media puts out a bunch of rail thin, airbrushed women out for everyone to see, this creates and reflects what “beauty” should look like and people stress themselves to be like this because they think that is what “beautiful” it. When in all honesty if you could see half these women in real life, you’d run for the hills.
