The News of the World was a weekly national "red top" tabloid newspaper published every Sunday in the United Kingdom from 1843 to 2011. It was at one time the world's highest-selling English-language newspaper, and at closure still had one of the highest English-language circulations. It was originally established as a broadsheet by John Browne Bell, who identified crime, sensation and vice as the themes that would sell most copies. The Bells sold to Henry Lascelles Carr in 1891; in 1969, it was bought from the Carrs by Rupert Murdoch's media firm News Limited. Reorganised into News International, a subsidiary of News Corporation, the newspaper was transformed into a tabloid in 1984 and became the Sunday sister paper of The Sun.
