Prince is DMCAing videos with his music in the background. This isn’t new. What’s new is that he’s sending takedown notices to Vine, a video service which hosts six second videos.
Vine launched less than three months ago, but the first DMCA takedown notices are already coming in. Among the first rights holders to file a grievance with Twitter is NPG Records, Princes music label. […] Chilling Effects, a watchdog site where Twitter publicizes such takedown requests, reveals that on March 22nd, NPG Records contacted the company and asked for eight videos to be brought down. As best we can tell, Twitter complied with the request, as none of the URLs are currently functioning.
