The Katie Couric story has a very interesting business twist, both in the short term for NBC and in the long-term for CBS; ad rates.  For NBC, the network will seek to capitalize on Katie's final days and weeks with the show by raising their :30 second spot rates.  In the meantime, the CBS Evening News, which is charging about $40K per thrity second spot expects that number to increase and equalize with its counter parts at ABC and NBC once the Katie Era begins. Now that the speculation over Katie's next move has been put to bed, let the speculation of The Couric Factor begin.
