• Steve Tignor and Kamakshi Tandon review Grace Lichtenstein's book A Long Way Baby and compare the WTA of 40 years ago to the what it is today.
I was struck by how much importance Lichtenstein attached to women's tennis at that time -- it was, in her's and [Billie Jean King's] minds, nothing less than the feminist movement made physical, made visual. I wonder if any professional tour in any sport has ever begun with so much political hope and baggage attached? For a progressive person like Lichtenstein, it was far more than a game, or a business, or a show. The [Virginia Slims Circuit] was proof that women could operate and succeed independently. Throughout the book, there's a sense that she's still a little stunned to see the whole enterprise happening, to see her fellow women doing what, until then, men had only done: negotiating endorsements, working out with a trainer, hanging out in a locker room together. All of these things, of course, are completely normal to us now -- a long way, for sure.
