Van Natta, who has long aspired to run a consumer Internet startup, is an obvious choice. Having fallen out of favor with Mark Zuckerberg, Facebook's fickle 24-year-old CEO, he is spending his exile running a music startup, called Project Playlist, out of an office building shared with Facebook. While Van Natta has managed to extricate Playlist from some of its legal troubles with the music labels, it hardly seems like a gig that encompasses his ambitions. Having worked for Elon Musk and Jeff Bezos as well as Zuckerberg, Van Natta seems capable of dealing with a testy owner-CEO like Rupert Murdoch.
