Gossip Girl (not the remake)
Who created it: Josh Schwartz and Stephanie Savage (and by extension: Cecily von Ziegesar who wrote the book the show is based on)
For whom: The viewer audience of the CW, which at the time aimed to appeal to a public comprised primarily of individuals aged 18 to 34 who identify as female, also to people interested in the idea of New York “High Society”
With what materials and metaphors: TV, for metaphors maybe a race
What impact: The show had a big impact of fashion and culture as a whole. There are a lot of memorable lines that survived to be part of pop culture.
On whom: Mostly on younger people (teens to mid twenties)
How: It became a very popular show with a lot of media coverage. It also spawned sub communities through message boards and social media.
I think they identified a public interested in the lives of the wealthy in NYC. People wanted to know the gossip and be “in” the social circles described in the show. I don’t think there’s really a counterpublic at play.
