Carl Bialik from WSJ writes "YouTube executives are finding it a slog to get all of the necessary permissions to license the songs and shows users are putting on the popular site, the Wall Street Journal reports. 'YouTube or its partners must locate parties ranging from studios to actors, and from music composers to the owners of venues, and get them to sign off. Where they don't succeed, YouTube risks being hit with lawsuits or having to take popular content down. "It's such a mess because the [entertainment companies] have all of these valuable assets that are just locked up with so many people who need to sign off on them," says YouTube Chief Executive Chad Hurley. "I don't know what it requires, if the government needs to be involved," Mr. Hurley laughs. "I don't know."'"
