Twenty20 (T20) cricket was first introduced by England in the 2003 season, which was played as a domestic inter-county competition. Following the success of the inter-county Twenty20 series, Cricket South Africa introduced Pro20 Cricket in the 2003/4 season with Standard Bank as the main sponsor.

Pro20 Cricket has brought back the crowds to domestic cricket in South Africa. There is almost no support from the public in the longer formats of domestic cricket, the MTN40 only draws crowds towards the end of the series, when the Protea players return and the SuperSport series, although extremely important to the national teams test ambitions never draws the crowds. However games in the Standard Bank Pro20 are regularly sold old, with or without Protea players.
