If you’ve uploaded a video to YouTube only to have it taken down, you’ve dealt with the Digital Millennium Copyright Act (DMCA). If you’ve ever been on Napster, Grokster, Bearshare, Kazaa, Morpheus, iMesh, LimeWire, The Pirate Bay, or any other torrent sharing site, you’ve dealt with the DMCA. If you’ve streamed TV episodes through a website only to see the website disappear overnight, you’ve seen the DMCA in action. So the DMCA basically stops someone from sharing copyrighted content online? Yes, but there’s a bit more to it.
