Introduction
Paid advertising on the internet is now a massive and truly global
business, and with every passing day it just keeps on getting bigger.
For example, in the first quarter of 2006, internet advertising revenues
reached a new high of $3.9 billion and by the end of the third quarter of
the same year, this figure had gone past $4 billion.
However, in the same Q3 period in 2007, internet advertising revenues
surpassed $5.2 billion, setting another new high and continuing the
trend of record breaking quarters that has been a constant ever since
the Internet Advertising Bureau started keeping records back in 1996.
