iAX: "Just how popular is K-On!? Apparently good enough to have many fans call the series the best series aired in the Spring 2009 season. Even though the first series was aired two years ago, I can’t seem to go to any anime related convention without seeing a K-On! cosplayer walking around. Not that it’s a bad thing. With the exceedingly large amount of fans this anime series has, it is no surprise that Bandai Entertainment has seen it fit to give K-On! not only an English dub, but a Blu-Ray release to boot."
