NEW YORK: Year-on-year and quarter-on-quarter, US online adspend continues to ride the internet thermal to record heights. So crows the Interactive Advertising Bureau and its enumerator PricewaterhouseCoopers.

The latter estimates that when the full-year numbers for 2007 are finally crunched, online ad revenues will have soared to $21.1 billion (€14.24bn; £10.72bn), an increase of 25% on 2006.

Moreover, revenues in last year's final three months totaled approximately $5.9bn, 13% up year-on-year, making it the highest quarter ever reported. All four quarters in 2007 posted record revenues. 

Crows IAB president/ceo Randall Rothenberg: "Interactive media continue their unabated growth. There is no media as measurable as interactive [wrong – what about direct mail?] and they provide products and services at the precise moment a consumer desires them.

"I applaud the industry on maintaining this extraordinary momentum of innovation, which has fundamentally changed the way we live today.” 

Taking up the promotional roundelay, PwC partner David Silverman harmonized: "The continued record growth evidences the importance and uniqueness of interactive media both to consumers and the marketers that are trying to reach them."
