Underground newspapers reached their hey-day in the late 1960's - mid 1970's in the US.
Examples
Underground newspapers began in the USA but the practice soon spread. In London Barry Miles, John Hopkins and others produced "International Times" which, following legal threats was renamed IT. Richard Neville arrived in London from Australia where he had edited a satirical magazine called "Oz". He launched a British version which was A4 as opposed to IT's broadsheet format. "Oz" was also more colourful, with designers like Martin Sharp.
Neville published an account of the Counter Culture called "Playpower" in which he described most of the world's Underground publications. He also listed many of the regular key topics from those publications including Vietnam, Black Power, Politics, Police Brutality, Hippies & Lifestyle Revolution, Drugs, Popular Music, New Society, Cinema, Theatre, Graphics, Cartoons etc.
