According to whois records, CBS Interactive has sold the domain name Juke.com to Media Saturn Holding GmbH.
CBS was going to use Juke.com for a music site but from what I have read, it never really got off the ground. That was around 2008.
From what I can tell, Media Saturn Holding GmbH is part of Metro AG / Metro Group. According to BusinessWeek.com:
METRO AG (DB:MEO) intends to explore options for Media-Saturn-Holding GmbH, according to two people with direct knowledge of the matter. METRO has hired Deutsche Bank AG to look for the options, which may include a sale, spinoff or initial public offering of the Media-Saturn, said the people, who asked not to be identified because the matter is private. Media-Saturn should be valued at about €5 billion, one of the people said.
So, what will happen to Juke.com or why it was likely purchased is yet to be known.
According to Wikipedia:
Metro AG, otherwise known as Metro Group, is a German global diversified retail and wholesale/cash and carry group based in Düsseldorf. It has the largest market share in its home market, and is one of the most globalised retail and wholesale corporations. It is the fifth-largest retailer in the world measured by revenues (after Wal-Mart, Carrefour, Tesco and Kroger).
