Galleries, Libraries, Archives, & Museums

I have avoided BDs up until now because I boycott Sony. I grabbed a blu-ray player dirt cheap on the 2nd-hand market b/c it was missing parts. I scrounged the needed parts so now I can watch BDs.

I obviously will not be buying an BDs since I boycott Sony. But what happens when I borrow a BD from a public library? Has Sony already been fully compensated by the time the disc goes on the shelf? Or does Sony get compensated somehow on a per-borrow basis?
