It's often probably at least a bit complicated. I cross-posted material between a couple of organizations (one of which is long gone) over a number of years via pretty much informal agreement. I also reused a fair bit of that material for other purposes. Everyone was OK with the state of affairs but who actually held the copyright? Who knows and I was certainly never going to bring it to a head. As a practical matter if CorporateMediaNews or the like don't care about something any longer, they mostly don't care if someone else makes use of it so long as it isn't embarrassing or misrepresenting the organization. In the end, I have created work that I've reused for a variety of organizations as well as independently and someone other than myself probably would claim copyright to but it's often been pretty loose.
