Anything (sufficiently creative) you create is automatically copyrighted by you, but according to Facebook's terms of service,
you grant us a non-exclusive, transferable, sub-licensable, royalty-free, worldwide license to use any IP content that you post on or in connection with Facebook
Though it's an interesting point; the Facebook ToS are a pretty weak way of effecting a copyright license, even worse than a click-through EULA.
I'm guessing they wouldn't be dumb enough to do so, but it'd be interesting if they tried to exploit that license grant to its maximum potential. For example, a number of musicians, and even major labels, post music videos on Facebook. If we take the terms at face value, that means Facebook gains a transferable license to use that music video, worldwide and royalty-free. So they could, for example, sublicense the video to be used in a Levi's television advertisement, without the original artist being paid--- if this license really does what it claims to do.
