The U.K.'s notorious phone hacking scandal led to the downfall of Rupert Murdoch's News of the World, the world's oldest Sunday newspaper. It started with the revelation that the paper's private investigator had hacked the voicemail of a murdered 13-year-old schoolgirl. Over 100 arrests were made, including the director of communications for Downing Street. The scandal prompted a public inquiry into the ethical practices of the British press and ultimately resulted in the closure of News of the World.
