Internet advertising revenues estimated to exceed $12.5 billion for full year 2005
The Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers (PwC) have announced that Internet advertising revenues for 2005 are estimated to exceed $12.5 billion, a 30% increase over the previous revenue record of $9.6 billion in 2004.
The 2005 Q4 revenues totaled a record $3.6 billion; making it the second consecutive quarter to surpass the $3 billion mark and the highest quarter reported. Fourth quarter revenues represent a 35 percent increase over the same period in 2004 and a 17 percent increase over Q3 of 2005.
The 2005 fourth quarter and full year online ad revenue figures were estimated by surveying and aggregating data from the top 15 online ad sellers. The results were then extrapolated to calculate the total estimated industry revenue figure.
