Can he save the music business? Caraeff grew Universal's mobile division until it became 45% of the parent's digital revenues, then headed all of digital for the leading label. Earlier this year he was tapped to run Vevo, the high-profile partnership between YouTube and record labels Universal and Sony designed to extract profits from music videos on the web (they're hugely popular, it turns out). Now EMI and Warner Music Group are mulling joining the venture, boosting its potential.

Do-gooder: Caraeff spends a week a year volunteering at an animal shelter in Utah.

Rio has led VEVO since the company was founded in 2009. Previously, Rio was EVP of Universal Music Groups eLabs, responsible for handling the companys electronic commerce initiatives, Internet exploitation, and new technology business opportunities worldwide.
