It is one of rugby's flagship events each year and attracts an average supporter base of 72,000.
In 2015, the tournament, which brings together England, Scotland, Ireland, Wales, France and Italy over 15 games, saw just over one million fans attend stadia such as Twickenham, the Millennium Stadium and Murrayfield.
