Palmer Luckey

Palmer Luckey's departure Thursday from Facebook and Oculus, the virtual reality company he co-founded in 2012, was sudden, but not entirely unexpected.

With the exception of his appearance in a Dallas, TX courtroom in January, he has been largely invisible since last September. But Luckey was one of the earliest cheerleaders of virtual reality — and many credit him with revitalizing interest in a technological field that many considered dead. And because of that, the speculation has already started about what his next move will be.
