When Quincy Smith leaves CBS Interactive in January, Ashe will take over the CEO's duties (but without the title). CBS Interactive had 58 million unique visitors in September and ranked No. 12 among Web properties, according to comScore. The business unit includes a number of prominent b-to-b sites, such as BNET, CNET and ZDNet. Ashe was CEO of CNET Networks when the company was acquired by CBS in 2008.
