A change-up at CBS Interactive (NYSE: CBS) ... Cyriac Roeding “has decided to leave his post heading the division to pursue various entrepreneurial endeavors.” Roeding joined what was then CBS Digital in 2005 to lead its wireless efforts and became head of the CBS Mobile division when it was created last year. Jeff Sellinger, who also joined in 2005, has been promoted to EVP and GM; he had been director, VP and, most recently, was responsible for overall operations as SVP.

The creation of CBS Mobile as a division last year was meant to show a cross-company commitment. Both Roeding and Sellinger have entrepreneurial roots: Roeding was co-founder and head of 12snap, while Sellinger was a founder of GoldPocket Wireless (acquired by Motricity). Release.
