I think this could also apply to the notion of "corporate culture". Something like there being the "executives", the "managers", and the umm..."direct reports"? line staff? Not sure what that would be. There's also some evidence that industries have cultures. For instance, companies within the tech industry share similarities. There seems to be a difference in kind though, between being able to identify a producer, a celebrity, and an observer within the kind of culture you're talking about, and a different idea of culture that somehow involves commonalities that people share. Like what about, say, "Chinese culture"? I think you can identify producers, celebrities, and observers (like umm...maybe Confucius? And celebrities...maybe umm...Mao?), but I'm not sure that defines Chinese culture substantially...but then, it doesn't sound like you're trying to define it. That's interesting.
If you develop further your criteria for producer, celebrity, and observer, it'd be fascinating to play with. Nifty constructs.
