Fullscreen, one of the top YouTube multichannel network companies, reached a deal with the National Music Publishers’ Assn. to settle copyright-infringement claims related to videos of song covers distributed by its affiliated creators.
Under the NMPA deal, Fullscreen will delete videos containing unlicensed music that appear on Fullscreen-managed channels. Meanwhile, Fullscreen-affiliated channels with videos containing music will be licensed under YouTube’s direct licenses with music publishers.
