funny, Youtube does not have ANY of the crazy copyright restrictions that stock companies have.
YouTube allows you to post videos with tattoos, videos of buildings like the Empire State Building, Hollywood sign, sports venues where you have to buy a ticket, people who are 'identifiable' by their clothes, videos that contain other artwork and photos.
I guess YouTube hasn't learned yet? (this is sarcasm)
The stock companies have been misinterpreting copyright laws for a long time. Hopefully some day they will start reading the copyright laws properly instead of what they have been doing.
