Regarded as a major event in British culture, the festival is inspired by the ethos of the hippie, counterculture, and free festival movements. It retains vestiges of these traditions, such as the Green Fields area, which includes sections known as the Green Futures and Healing Field. After the 1970s, the festival took place almost every year and grew in size, with the number of attendees sometimes being swollen by gatecrashers. Michael Eavis hosted the first festival, then called Pilton Festival, after seeing an open-air Led Zeppelin concert at the 1970 Bath Festival of Blues and Progressive Music. The festival's record crowd is 300,000 people, set at the 1994 festival, when headliners the Levellers performed a set on The Pyramid Stage.
