Rolling Stone is a biweekly US magazine focused on music, politics, and popular culture that was founded in 1967 in San Francisco. It was known for its political coverage in the 1970s and coverage of rock music. In the 1990s, it shifted its focus more towards pop culture and celebrities, which received criticism for emphasizing style over substance. Recently, it has resumed a mix of in-depth political stories and increased its circulation. The founder and publisher, Jann Wenner, moved the headquarters to New York in 1977 and has grown circulation to over 1.5 million by 2006 through responding to musical trends.
