In the U.S. the term "underground newspaper" generally refers to an independent (and typically smaller) newspaper focusing on unpopular themes or counterculture issues. Typically, these tend to be politically to the left or far left. More narrowly, in the U.S. the term "underground newspaper" most often refers to publications of the period 1965–1973, when a sort of boom or craze for local tabloid underground newspapers swept the country in the wake of court decisions making prosecution for obscenity far more difficult. These publications became the voice of the rising New Left and the hippie/psychedelic/rock and roll counterculture of the 1960s in America, and a focal point of opposition to the Vietnam War and the draft.
