The film was so successful that it was reissued to theaters in 1965. A year later, CBS purchased the television rights for $450,000. CBS planned to televise the film on September 23, 1966, but three days earlier, Valerie Percy, daughter of Illinois senate candidate Charles H. Percy, was murdered. As her parents slept mere feet away, she was stabbed a dozen times with a double-edged knife. In light of the murder, CBS agreed to postpone the screening, but as a result of the Apollo pad fire of January 27, 1967, the network washed its hands of Psycho, and shortly afterward Paramount included the film in its first syndicated package of post-1950 movies, "Portfolio I". WABC-TV in New York City was the first station in the country to air Psycho (with some scenes significantly edited), on its late-night movie series, The Best of Broadway, on June 24, 1967. Following another successful theatrical reissue in 1969, the film finally made its way to general television airing in one of Universal's syndicated programming packages for local stations in 1970. Psycho was aired for twenty years in this format, then leased to cable for two years before returning to syndication as part of the "List of a Lifetime" package.
The film was re-released on September 20 & 23, 2015, as part of the "TCM Presents" series by Turner Classic Movies and Fathom Events.
