Pornography in the United States

Pornography has existed since the origins of the United States, and has become more readily accessible in the 21st century. Advanced by technological development, it has gone from a hard-to-find "back alley" item, beginning in 1969 with Blue Movie by Andy Warhol, the Golden Age of Porn (1969–1984) and home video, to being more available in the country and later, starting in the 1990s, readily accessible to nearly anyone with a computer or other device connected to the Internet.
