It's very interesting to see the differences between two (almost) identical videos available on YouTube.
The first one was uploaded by Universal Music, the owner of the distribution rights, and is displayed using a new YouTube player in
the new interface, available as an option for most other videos. Next to the video there's an AdSense banner and the video can't be embedded ("embedding disabled by request).
The second video was uploaded by a normal YouTube user, is displayed using the old player, the new interface is an option, there's no ad next to the video and you're able to embed the video into your site.
The first video has more than 14 million views, while the second one only has 378,000. I'll leave the comments to you.
