The Yippie "New Nation" concept called for the creation of alternative, counterculture institutions: food co-ops; underground newspapers and zines; free clinics and support groups; artist collectives; potlatches, "swap-meets" and free stores; organic farming/permaculture; pirate radio, bootleg recording and public-access television; Squatting; free schools; etc. Yippies believed these cooperative institutions and a radicalized hippie culture would spread until they supplanted the existing system. Many of these ideas/practices came from other (overlapping and intermingling) counter-cultural groups such as the Diggers, the San Francisco Mime Troupe, the Merry Pranksters/Deadheads, the Hog Farm, the Rainbow Family, the Esalen Institute, the Peace and Freedom Party, the White Panther Party and The Farm. There was much overlap, social interaction and cross-pollination within these groups and the Yippies, so there was much crossover membership, as well as similar influences and intentions.
