Do you remember the "Battle of the es" tennis match with Billie Jean King?

I'm watching Oprah and they are showing powerful femininst leaders like Gloria Steinhem. They showed the tennis match with Billie Jean King. It was in 1973 so it was the year I was born so of course, I don't remember it! I was a big tennis player though from grade school through college and I even was nationally ranked. I just wanted to know how exciting this match was since they said that 50 million people watched! That's HUGE for any sporting event like Superbowl huge. Wouldn't you love to see someone like Venus or Serena Williams play a man for fun?
