On March 12, 2007, during a 9 p.m. airing of an Ion Life rebroadcast of a Tom Brokaw-hosted NBC special, "State of U.S. Health Care", on Phoenix, Arizona TV station KPPX-TV, a station employee inserted about 30 seconds of a pornographic film into the broadcast, prompting telephone calls to local news media outlets and the local cable provider, Cox Communications. Parent company Ion Media Networks conducted a rigorous investigation into what they called "an intolerable act of human sabotage", and shortly thereafter, announced that the employee found to be responsible had been fired, threatening further legal action.
