Here are four interesting places that you might want to poke around in to find critical inquiries and analysis on popular culture:
Bitch Magazine: A Feminist Response to Popular Culture – This magazine is also based out of Portland. They have a variety of events and book clubs that happen here locally.
Portland Center for the Humanities – This organization is housed at PSU and, “promotes rigorous humanistic inquiry into the languages, histories, and ideas that shape our ways of life, as well as those that offer a means of positively transforming them.” Many of their events connect in one way or another to popular culture. I would highly encourage you to attend an event over the course of the term.
