KUALA LUMPUR - The Badminton World Federation (BWF) on Sunday announced a new tournament structure, with increased prize money, as it looks to raise the sport's profile and ramp up revenues.

The new tour series, featuring six levels, will kick off next year and run until 2021, with at least $1 million up for grabs in each of its top four events.

Federation president Poul-Erik Hoyer Larsen announced the changes following a BWF council meeting in Kuala Lumpur, saying: "The time is right for badminton to soar even higher."

"Our key goals are to showcase our sport at a high level of presentation and competitiveness, to increase television coverage for the sport and to increase the star quality and popularity of the top players globally", Her added.

The Level 1 end-of-season finale to be played in China will feature $1.5 million in prize money, while the three Level 2 events - in China, England and Indonesia - will carry $1 million prizes, a BWF statement said.

There will be five Level 3 events with $700,000 prize money, seven Level 4 tournaments with $350,000 to be won and 11 in level 5 ($150,000).

The tour will involve an estimated total of 37 events, including the Level 6 open category in which BWF member associations can apply for sanctioning.

The sport has struggled to gain visibility in recent years, losing out to more glamorous rivals such as NBA basketball, soccer and tennis.

An ill-advised push to "sex up" the sport's image saw the BWF ask women players to wear skirts, a proposal which was finally shelved in 2012 following howls of protest.

New scoring, advertising initiatives and even new shuttlecocks and court colors have also been considered as badminton looks to shed its staid image and stand out in the digital age.
