In 2001, Qatar became the first country in the Middle East to hold a women's tennis tournament with the inauguration of its Qatar Ladies Open tournament. Doha also hosts International Tennis Federation (ITF) ladies tournaments. Since 2008, the Sony Ericsson Championships (equivalent to the ATP's season-ending Championships) has taken place in Doha, in the Khalifa International Tennis Complex, and features record prize money of $4.45 million, including a check of $1,485,000 for the winner, which represents the largest single guaranteed payout in women's tennis.
