Re: Isn't it bad?
But there won't be any real labour cost: employees don't have a DB of copyrighted material in their head, so can't compare what they are watching to anything subject to copyright.
The solution will be technological: like the Shazam mentioned above. Or closure. Or (Netflix-like) subscription to cover the cost of reviewing. Or more advertising. Or all of the above.
So much stuff we see on utub is obviously ripped from another user and zoomed or cropped and re-uploaded. Sometimes the uploader states in the description "I don't own the copyright in this material" : perhaps Google could run a filter on that or similar phrases in description, removing all such vids, for a start?
