text: 2009–2014: Championship In 2009 Super League was expanded to 14 teams, with two additional teams being promoted from National League One. In turn, two additional teams were promoted from National League Two to National League One at the end of the 2008 season, reducing the number of teams in National League Two to 10. National Leagues One and Two were then rebranded as the Championship and Championship 1 respectively, with the change being implemented in time for the 2009 season. Championship 1 was later rebranded to League 1. During this period, a system of licensing was put in place which meant there was no automatic system of promotion and relegation between the Championship and Super League, although promotion and relegation continued between the Championship and League 1. Widnes Vikings were promoted to Super League from the Championship via the licensing system in 2011.
  The record crowd for a club game at this level of competition was set in 2017 at KCOM Craven Park for the opening fixture of the season between Hull Kingston Rovers and Bradford Bulls with Rovers winning 54–24 in front of a crowd of 8,817. The crowd record for regular season attendance was also broken in 2008 with an average of 2,205 spectators at each game.
  2015–2018: Super 8s
  In 2013, Super League clubs agreed to reduce the number of clubs in the competition to 12 and return to an amended system of promotion and relegation with a 12-club Championship competition. These changes came into effect for the 2015 season.
