Whether it's winning new fans or appealing to TV audiences, sport is always trying to renew itself.

The latest to undergo the modern day makeover is tennis.

The International Premier Tennis League is contested by teams with elite men, women, doubles and legends players.

The likes of Serena Williams, Maria Sharapova, Roger Federer and Andy Murray are all signed up, and it got underway in Manila this week with events also planned for Delhi, Dubai and Singapore - the four cities represented by the teams.

The players be familiar, the rules less so.

The man behind the revolution is Mahesh Bhupathi, who won a career grand slam in mixed doubles as a player but is now the founder and president of the new tournament.
