(Los Angeles Times) A communications executive for media mogul Barry Diller went from relative obscurity to global pariah after an insensitive tweet about AIDS and Africa went viral.

Justine Sacco, a director of communications at Diller’s IAC, whose holdings include television production company Electus, dating sites Match.com and OKCupid as well as the video site Vimeo, tweeted “Going to Africa. Hope I don’t get AIDS. Just kidding. I’m white!”

Then she boarded a flight from London to Africa and all heck broke lose on Twitter as her tweet circulated way beyond the few hundred followers she had and became news.
