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.[1] 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.[2]
