The Sun is a British tabloid newspaper, published by the News Group Newspapers division of News UK, itself a wholly owned subsidiary of Rupert Murdoch's News Corp. It was founded as a broadsheet in 1964 as a successor to the Daily Herald, and became a tabloid in 1969 after it was purchased by its current owner. The Sun enjoyed the largest circulation of any daily newspaper in the United Kingdom, but was overtaken by freesheet rival Metro in March 2018.
