As reported by Steve Knopper in a June 24th, Rolling Stone article; five rock radio stations in major U.S. cities switched formats in recent months after ratings dropped for six consecutive years. This does come at an odd time since, as explained by Knopper in his article, rock albums have dominated the charts the past few months. Artists such as Coldplay, Green Day, Audioslave, System of a Down, Bruce Springsteen, Nine Inch Nails, the Dave Matthews Band, and Rob Thomas have all experienced success on the billboard charts this past spring and summer.
