OZ was first published as a satirical humour magazine between 1963 and 1969 in Sydney, Australia and, in its second and more famous incarnation, became a “psychedelic hippy” magazine from 1967 to 1973 in London. 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.
