The problem with "Pet Tales with Greta" was that it only convincingly resembled a Discovery Channel show. Its host and executive producer: Greta Van Susteren, a former Fox News personality who willingly left that cable outlet after network boss Roger Ailes faced numerous allegations from female Fox staffers of sexual misconduct and sexual harassment. A similar scandal ensnared popular Fox News anchor and "The O'Reilly Factor" host Bill O'Reilly, fired by the channel after The New York Times discovered that the network paid $13 million to settle sexual harassment claims made against him. Along with NFL legend Terry Bradshaw, and singer Katherine McPhee, O'Reilly was a guest on "Pet Tales with Greta," a celebrity interview show about animals.
