Q: Question: How old was Ross when he was promoted from the Disney Channel to Walt Disney Studios? Passage:Ross and Bonnett were subsequently promoted at Disney, along with others from the Disney Channel, and credited for Hannah Montana's broad reaching success across TV, music, and live tours, the model first proposed and put into motion by Roundhouse producers at Nickelodeon, but blocked by the network during the time Ross and Bonnett were there. That decision turned out to be shortsighted by Nickelodeon, and when proposed again to the then underutilized Disney Channel as a tie-in to the underperforming Hollywood Records (Disney Music Group), the concept proved inherently valuable enough that, as the complaint filed against Disney in 2007 in Los Angeles claimed, Rock and Roland was misappropriated by Disney and produced under the name Hannah Montana. For their key roles in bringing Hannah Montana to Disney, Rich Ross was elevated from the Disney Channel to Chairman of Walt Disney Studios in October 2009, forced to resign April 2012, and Adam Bonnett upped to Senior Vice President, Original Programming, Disney Channel.
