Kolkata Knight Riders is the franchise representing Kolkata in the Indian Premier League, a Twenty20 cricket tournament. Till IPL3, the team was led by Sourav Ganguly,who unfortunately remained unsold for the fourth season, and coached by Dav Whatmore. Sourav Ganguly was the team's Icon Player for the first three seasons. The official theme of the team is Korbo, Lorbo, Jeetbo Re (Bengali for We will do it, Fight for it, Win it) and the official colors are purple and gold. As per the recent study done by a UK based brand valuation company, Kolkata Knight Riders (KKR) are ranked as the second most valuable franchise brand at US$46 million. Celebrity co-owner Shahrukh Khan’s hard-selling of the KKR brand has counteracted the team’s poor on-field performance. They are the only team to have never made the semi-finals.
