Blocking of YouTube videos in Germany
The blocking of YouTube videos in Germany was part of a former dispute between the video sharing platform YouTube and the Gesellschaft für musikalische Aufführungs- und mechanische Vervielfältigungsrechte (GEMA, or "Society for Musical Performance and Mechanical Reproduction Rights" in English), a performance rights organization in Germany. According to a German court in Hamburg, Google's subsidiary YouTube could be held liable for damages when it hosts copyrighted videos without the copyright holder's permission.
