Pop Culture Isolation is basically a case of pop culture myopia of sorts. Where celebrity, music genres, media or events that are huge and significant in one subculture or ethnic group, but elsewhere nobody knows it exists or is indifferent to it altogether. We're not talking about separate countries here, but within the same country or region. A lot of this is especially prevalent in entertainment, especially music. Radio is probably the main cause of this as radio is very isolated in terms of programming and format. Though some just see all of this as another form of segregation.
