Artists like platinum-selling superstar rapper Chamilllionaire are taking advantage of the new opportunities of video sharing and social network sites to build reputation and business.

I interviewed him earlier this week at Advertising 2.0 in New York.  He told me that reality TV is indicative of consumer demand for video about people’s lives.  He says that includes stars like himself.  So, he’s taken to traveling with a videographer.  He says there is big demand for content.

Chamillionaire told me as a result of his online presence, he has sold 4 million ring tones from his song "Ridin’ Dirty."  He says this is the most ringtones sold by a rap artist.

I will catch up with rapper in Hollywood on Tuesday.  He will be on panel moderated at OnHollywood moderated by Quincy Jones, III.
