In a 2019 television segment on Last Week Tonight featuring prominent purported mediums including Theresa Caputo, John Edward, Tyler Henry, and Sylvia Browne, John Oliver criticized the media for promoting mediums because this exposure convinces viewers that such powers are real, and so enable neighborhood mediums to prey on grieving families. Oliver said "...when psychic abilities are presented as authentic, it emboldens a vast underworld of unscrupulous vultures, more than happy to make money by offering an open line to the afterlife, as well as many other bullshit services."
