NEW YORK: Online ad revenues in the US climbed to $4.9 billion (€3.63bn; £2.46bn) in the first quarter of 2007, a year-on-year hike of 26%, according to data compiled by PricewaterhouseCoopers for the Interactive Advertising Bureau.

Says IAB president/ceo Randall Rothenberg: "The continued growth of online ad revenues clearly illustrates marketers' increased comfort with the extraordinary vitality and accountability of this medium."

Adds PwC director Peter Petrusky: "We may expect continued strong revenue growth buoyed by an expanding broadband subscriber base."

Record gains in Q1 online ad sales contrast with declines in traditional media, including a 7.2% drop in spending on US broadcast television networks, reports TNS Media Intelligence. National and local newspaper ad revenues also fell respectively by 5.3% and 4.6%.
