On 20th September 1973, it was woman versus man, champion versus champion.

In front of 30,000 fans and a global audience of some 50 million, the iconic tennis match they said would never happen, was about to get underway.

Billie Jean King was the darling of American tennis: a global, multi-major winning superstar at the peak of her powers.  Across the net was Bobby Riggs; a long-time retired pro, but a fast talking hustler and chauvinist showman, who proclaimed his desire to put women back in their place.

For the media, their unlikely courtship was a match made in heaven; for women’s liberation, it was a golden opportunity to take a huge step toward equality; and for ordinary Americans, it was a welcome distraction from Vietnam and the shame of the Watergate scandal.
