The ECB40, last known as the Yorkshire Bank 40 (YB40) for sponsorship reasons, was a forty-over limited overs cricket competition for the English first-class counties. It began in the 2010 English cricket season as a replacement for the Pro40 and Friends Provident Trophy competitions. Yorkshire Bank were the last sponsors, taking over the naming rights from their parent company Clydesdale Bank for the 2013 edition. Warwickshire won the inaugural tournament. The competition was replaced by a 50-over tournament, to bring the domestic game in line with the international game from 2014 on—the Royal London One-Day Cup.
