CBS’ reliance on steady shows has helped the network win more ad dollars than its rivals, Advertising Age reports.

The network drew about $4.03 billion in ad dollars from Sept. 1, 2008 through May 17, 2009, more than ABC’s $3.67 billion or NBC’s $3.02 billion, the trade paper says, citing figures from TNS Media Intelligence.
