If it just to be used to measure the popularity of copyright vs non-copyright video, then why
does it need Viacom to do it. I am sure that google itself has more facilities for doing this.
Anyway, what is a non-copyright video? Unless it is specifically placed in the public domain
or (very unlikely in the case of videos) the copyright has expired then every video, whether a
clip from a movie or TV show or one recorded on a camcorder or mobile phone, is copyright. So
as there will be almost no non-copyright videos on youtube (or anywhere else on the net), the
popularity of copyright videos must be almost infinitely higher than that of non-copyright
