Skate punk broke into the mainstream in the mid-1990s, initially with the Northern California-based skate punk band Green Day and in the late 1990s with the Southern California-based pop punk band Blink-182 as well who all achieved massive worldwide commercial success. Green Day's album "Dookie" (1994) sold 10 million copies in the United States and another 10 million copies worldwide. Soon after the release of "Dookie", The Offspring released the album "Smash". The album sold over 14 million copies worldwide, setting a record for most albums sold on an independent label.
