The Psychic Friends Network (PFN) was a telephone psychic service operating in the United States in the 1990s. The company's infomercials were aired frequently on late night television at that time. In 2012, the business began to migrate to online services. Mark Edward, who worked as a telephone "psychic" for the network, has become a vocal critic of the PFN, and all psychics, saying that "the psychic business is built on lies". His book Psychic Blues details what it was like to work for PFN.
