In the late 1960s and into the 1970s, the underground comics movement inspired two new comics in the UK: "Oz" and "Nasty Tales" were launched with the underground premise of counter-culture rebellion. "Oz" notoriously featured the children's character "Rupert the Bear" performing sexual acts. Both magazines were tried at the Old Bailey under the Obscene Publications Act because of their content. The "Oz" defendants were convicted, although the conviction was overturned on appeal. The "Nasty Tales" defendants were cautioned. However, both these comics ceased publication soon after their trial, as much due to the social changes at the end of the counter-culture movement as any effect of the court cases. These were always adult magazines, not aimed at the mainstream children's market.
