Msc. Kvetch: What does it mean for a battle to be “lost by the media”?

1.  What does it mean for a debate to be “media driven” or a battle to be “lost by the media”? In my last post, I noted that until a few weeks ago, I’d never heard of a “power morcellator.” Nor had I heard of the AAGL–The American Association of Gynecologic Laparoscopists.
