YouTube's Content ID is an identification and management tool that allows content providers to determine how their videos will appear on the popular online video site. As of last week, over 1,000 partners had signed up for Content ID. However, the tool only provided limited stats on videos.
Today, Content ID is being combined with YouTube Insight to provide more robust analytics.
For example, Sony Music can view analytics on the JK Wedding Entrance video, which, though uploaded by a third party, uses a song by Sony artist Chris Brown.
This is a great tool for companies and marketers who want to track their viral content, such as songs and videos.
