U.S. online advertising increases in 3Q


NEW YORK -- Internet advertising reached a new high of $4.2 billion in the third quarter, marking the eighth consecutive quarter of growth, according to a study released Tuesday.

The estimate comes from PricewaterhouseCoopers LLP, which conducted the quarterly online advertising study for the Interactive Advertising Bureau, an industry trade group.

U.S. revenues in the third quarter grew 2 percent from the $4.1 billion in the second quarter and 33 percent from $3.1 billion a year ago.

"The consistent growth of online advertising is a clear indication that marketers continue to embrace the true power of interactive advertising," said Sheryl Draizen, the trade group's general manager.

PricewaterhouseCoopers breaks down revenues by ad format only for its midyear and year-end reports. Keyword ads displayed alongside search results generally are the most lucrative.

Despite continued growth, Internet advertising accounts for only about 5 percent of all U.S. advertising revenues.
