The film's final act reveals the ultimate horror of the corporate ethos. When Howard Beale begins preaching Arthur Jensen’s gospel—a message of corporate nihilism that the audience finds depressing—his ratings plummet. In a chilling board meeting, the executives (Diana, Frank Hackett, and others) casually discuss and ultimately authorize Beale's assassination live on air to boost ratings for the season premiere.
The ending is a 'perfect' corporate solution: Beale is murdered by the very terrorist group Diana had signed to the network for a reality show. The film concludes with a cynical narration: 'This was the story of Howard Beale, the first known instance of a man who was killed because he had lousy ratings.' The twist reveals that the network doesn't just exploit life; it happily manufactures death if the numbers justify it.
