The Six Nations and Sanzaar unions have agreed to market their media and commercial rights collectively for the first time, in an arrangement described as unique in world sport. Under the new model, a dedicated rights management agency will oversee joint sales, with revenue shared across both hemispheres. Southern hemisphere unions will receive a share of profits from Six Nations broadcasting and commercial deals, as well as from British & Irish Lions tours, while the Six Nations countries will benefit from Rugby Championship rights income and deals tied to the Rugby's Greatest Rivalry series between South Africa and New Zealand.
