OZ

Oz was first published as a satirical humour magazine between 1963–69 in Sydney, Australia and, in its second and more famous incarnation, became a "psychedelic hippy" magazine from 1967 to 1973 in London, England. Strongly identified as part of the underground press, it was the subject of two celebrated obscenity trials, one in Australia in 1964 and the other in the UK in 1971.
he magazine regularly enraged the British Establishment with a range of left-field stories including heavy critical coverage of the Vietnam War and the anti-war movement, discussions of drugs, sex and alternative lifestyles, and contentious political stories, such as the magazine's revelations about the torture of citizens under the rule of the military junta in Greece.

In 1970, reacting to criticism that Oz had lost touch with youth, the editors put a notice in the magazine inviting "school kids" to edit an issue. The opportunity was taken up by around 20 secondary school students (including Charles Shaar Murray and Deyan Sudjic), who were let loose on Oz #28 (May 1970), known as "Schoolkids OZ". This term was widely misunderstood to mean that it was intended for school children, whereas it was a statement that it had been created by them.
Oz was one of several 'underground' publications targeted by the Obscene Publications Squad, and their offices had already been raided on several occasions, but the conjunction of schoolchildren and arguably obscene material set the scene for the infamous Oz obscenity trial of 1971.
The trial brought the magazine to the attention of the wider public. John Lennon and Yoko Ono joined the protest march against the prosecution and organised the recording of "God Save Oz" by the Elastic Oz Band to raise funds and gain publicity.
