the video, MTV announced that it would continue to air it. The Source, through CEO Raymond "Benzino" Scott, called for the video to be pulled, the song removed from the album and Eminem to apologize publicly to Jackson. In 2007, Jackson and Sony bought Famous Music from Viacom, giving him the rights to songs by Eminem, Shakira, Beck and others.
