The Leveson Inquiry is/was public inquiry into cultures, practices and ethics of the British press. This inquiry looks into the News international phone hacking scandal for publicity of private and personal information about celebrities and general people.
One of the main ideas that revealed the disgust the media is involved with Milly Dowlers murder. A young teenager was murdered and the body was supposedly never found, however when writing stories and gathering info the media, with the polices consent, hacked into the young girls phone and texted her parents to give the false idea that she was still alive, they did this to keep the story going and make more sales.
The Levenson study was created to reveal all of this corruptness and how the media needs to change, this was 10 years ago and the world has hardly changed.
