Nobody in my high school except myself and my friends listened to alternative music at all. Then Nirvana's "Smells Like Teen Spirit" came out, and at first it was only popular among my friends, but suddenly it spread like wildfire, in a way that was completely unprecedented for an alternative type song to do at the time, and by the time winter rolled around everyone at my school loved Nirvana. After that came groups like Pearl Jam and the hair metal and hard rock that had totally dominated the consciousness of my classmates rapidly began to fade away. It was really pretty incredible how fast it happened. In retrospect, hair metal was kind of running out of steam, and changing to be a lot less flashy, by the time Nirvana came along, but it's definitely true that "Smells Like Teen Spirit" was the thing that really knocked it out of the game.
