Bloomberg: IBM CEO Ginni Rometty is scheduled to attend Allen & Co.’s annual conference in Sun Valley, Idaho, underscoring a growing number of female and non-media attendees. Women still make up a small percentage of the attendees at the conference — fewer than 25 of the more than 300 invited. Yet that’s almost twice the number from last year. Media moguls still feature prominently at the conference, including Rupert Murdoch, Barry Diller, Les Moonves, Bob Iger, Casey Wasserman and Harvey Weinstein.
