Universal Music Group is stepping up pressure against popular online sites YouTube and MySpace, accusing them of infringing the copyrights of its artists' music videos.  
Universal chief executive Doug Morris described video site YouTube and News Corp.'s social networking site MySpace as "copyright infringers" during a Merrill Lynch investors' conference speech on Tuesday (Sept. 12) that was closed to the press.  
"The poster child for (user-generated media) sites are MySpace and YouTube," said Morris, according to a transcript obtained by Reuters. "We believe these new businesses are copyright infringers and owe us tens of millions of dollars."  
He added, "How we deal with these companies will be revealed shortly."
