MediaBuyerPlanner: CBS is the most advertising-dependent of the major media companies, according to a breakdown of its post-Viacom spin-off filed with the Securities and Exchange Commission, MediaPost reports. Seventy-two percent of its revenues during the first quarter of 2006 came from advertising sales. The old Viacom derived less than half of its revenues from advertising sales.

CBS' biggest growth area came from licensing its TV programs to other outlets. Such licensing fees now account for 13 percent of the company's revenues up from nine percent a year ago. Affiliate related revenues were flat at seven percent, as were publishing related revenues at 5 percent. "Other" revenues declined from four percent to three percent of CBS' base.
