After the 1969 Stonewall uprising in New York City was covered on the mainstream news channels, showing images of gay men rioting in the streets, gay male culture among the working classes, people of color, street people, radical political activists and hippies became more visible to mainstream America. Groups such as the Gay Liberation Front formed in New York City, and the Mattachine Society, which had been in existence and doing media since 1950, gained more visibility as they addressed the crowds and media in the wake of the uprisings in Greenwich Village. On June 28, 1970 the first Christopher Street Liberation Day was held, marking the beginning of annual Gay Pride marches.
