OCIA.net has posted their 2008 CES Coverage: Jook article.  Below is a direct quote from the article:

“Jook, a subsidiary of Razer, is a wireless technology standard that allows any portable music player to act like a personal radio station. Basically, Jook wirelessly broadcasts songs to people in the immediate vicinity. Think of Jook as “social networking meets music”. With the success of social networking sites like Myspace and Facebook, it only makes sense to expand on this growing market.“
