Q3 US Online Ad Revenues, 2001-2013 [CHART]

Chart - Q3 US Online Ad Revenues, 2001-2013

Online ad revenues continue to climb to new heights, growing 15% year-over-year in Q3 from $9.26 billion to $10.69 billion, according to the latest quarterly revenue report from the Internet Advertising Bureau and PricewaterhouseCoopers. That makes Q3 the latest record-setting quarter, up from the previous peak of $10.31 billion set in the fourth quarter of 2012. The record won’t stand for long, though: if current growth trends continue, online ad revenues could approach $12 billion during the fourth quarter of this year.

Meanwhile, the Q3 rate marks the 14th consecutive quarter of double-digit year-over-year growth. It also represents 4.2% growth from Q2′s $10.26 billion in revenues.

While the growth rates remain strong, they couldn’t quite match last year’s pace. During Q3 2012, revenues were up 18% year-over-year and 6% quarter-over-quarter. Both of those rates were the highest that had been seen in several quarters. (The second quarter of this year matched that year-over-year growth rate of 18%.) Read the rest at MarketingCharts.
