In the United States 1950s, satire was introduced into American stand-up comedy most prominently by Lenny Bruce and Mort Sahl. As they challenged the taboos and conventional wisdom of the time, were ostracized by the mass media establishment as "sick comedians". In the same period, Paul Krassner's magazine "The Realist" began publication, to become immensely popular during the 1960s and early 1970s among people in the counterculture; it had articles and cartoons that were savage, biting satires of politicians such as Lyndon Johnson and Richard Nixon, the Vietnam War, the Cold War and the War on Drugs. This baton was also carried by the original National Lampoon magazine, edited by Doug Kenney and Henry Beard and featuring blistering satire written by Michael O'Donoghue, P.J. O'Rourke, and Tony Hendra, among others. Prominent satiric stand-up comedian George Carlin acknowledged the influence "The Realist" had in his 1970s conversion to a satiric comedian.
