The ATP has announced reforms to the way it operates, with profit sharing among tournaments and expanding Masters events.
ATP finances will also now be completely transparent under the new plan.
Expansion of Masters events are a key part of ATP plans, with the Madrid Open, Internazionali BNL d’Italia and Shanghai Masters all to grow to a 96-player draw played over 12 days from 2023.
The Canadian Open and Cincinnati Masters will follow suit from 2025 to bring all five events in line with Indian Wells and Miami.
“Our sport has huge upside and stands on the cusp of a new era of growth," ATP chairman Andrea Gaudenzi said.
"Fulfilling our potential requires us to be united, pursue new growth opportunities and focus on what matters most: the fans.
"OneVision gives us a game plan to do just that. Its launch represents a game-changing moment for the Tour and a huge collective effort across our sport.
"I’m incredibly excited for what’s to come.
"Shifting everybody's mind into the future has been the most difficult part.
"But I think overall we kept being very persistent, the evidence we provided, a lot of data, a lot of information, a lot of material and ultimately we convinced, I wouldn't say everybody, but the majority.
"It's a little bit like trying to engage employees in a start-up.
"You give them stock options, you give them a share of the upside and success. That's where you create the motivation and the drive. And that's where you create alignment."
Phase Two of the plan will seek to unite tennis governance to create a uniform structure across tennis, but there has been no timeline offered for when that might happen.
