World Team Tennis was founded by Billie Jean King and a group of the world’s top players, united by a belief that tennis could be more than an individual pursuit — and more than just a sport.

From day one, WTT broke with convention. It was the first professional sports league to feature men and women competing together on the same team. At a time when gender equality in sport was still a radical idea, WTT made it a reality.

But it wasn’t just the format that stood out. WTT brought energy, personality and spectacle to the court. Matches were team-based, loud, and unapologetically colourful. Players wore bold kits. Music played between points. The league was rooted in entertainment as much as athleticism.

Set against the cultural backdrop of the 1970s, WTT stood for more than tennis — it stood for progress, expression, and challenging the status quo.
