Kenneth “KC” Estenson is leaving his post as VP, digital media at Disney-ABC Cable Networks Group to join CNN.com as SVP/GM in September, a rep for the Time Warner (NYSE: TWX) owned CNN.com said. Estenson fills the vacancy left by David Payne, who we reported left the post back in April to start an online ad company.

It’s worth noting that CNN.com went outside the company to fill the post. That said, hiring an executive from a rival is always tempting. Estenson has been with Disney (NYSE: DIS) since 2001. During the past seven years, he oversaw the digital media businesses across Disney’s online, on-demand, mobile, broadband and wireless products and worked on Disney Channel Worldwide, SOAPnet and ABC Family.  He also helped manage the creation of ABC News Now’s broadband service. In his new post, he’ll be reporting to Susan Grant, EVP, CNN News Services.
