Obama, McCain embrace web ads

Aug. 7 - Web ads are being used extensively by both John McCain and Barack Obama to quickly get the attention of the public and cable outlets.

In fact, the campaigns of both John McCain and Barack Obama will collectively spend $13 million to advertise on television over the next three weeks during the Summer Olympics.
