Ms. Ross, who for the past four years held the title of executive vice president of sales, was Mr. Abruzzese's deputy and was considered the leading contender for the position along with Scott McGraw, CBS executive vice president for network sports sales and marketing.
A CBS spokesman said that
"When the network sales force is firing on all cylinders, it's difficult to give it to any one other than the No. 2," said a CBS staffer, who spoke on the condition of anonymity.
Ms. Ross, as Mr. Abruzzese also did, will oversee sales at CBS's TV and Internet operations, as well as at sister Viacom network UPN.
