Editing The Rugby Championship (section)

===Format===
The series is played on a home-and-away basis. From the first tournament in 1996 until 2005, the three teams played each other twice. From then until 2012, each team played the others three times, totally six games per team, except in the [[Rugby World Cup]] years of [[2007 Rugby World Cup|2007]] and [[2011 Rugby World Cup|2011]] when the series reverted to a double round-robin.

With the addition of [[Argentina national rugby union team|Argentina]], in 2012, the format once again reverted to a double round-robin, meaning each team again played six games. For 2015, to provide the teams longer preparation time ahead of the [[2015 Rugby World Cup]], each side played the others' teams only once each. This format was also adopted for the [[2019 Rugby Championship|2019 Tournament]].
