Online advertising revenues continue to hit record highs. The Interactive Advertising Bureau released a new report today finding that revenues for the first half of 2013 hit a record high of $20.1 billion. That’s an increase of 18% over the same period last year ($17 billion).

The second quarter also saw an 18% year-over-year increase at $10.3 billion, up from $8.7 billion. Here’s a look back:

“Digital has steadily increased its ability to captivate consumers and then capture the marketing dollars that follow,” said IAB President and CEO Randall Rothenberg. “Mobile advertising’s breakneck growth is evidence that marketers are recognizing the tremendous power of smaller screens. Digital video is also on a positive trajectory, delivering avid viewership and strong brand-building opportunities.”

Last year, mobile ad revenue jumped a whopping 83% hitting a record $8.9 billion. It will be interesting to see what this year’s numbers look like when they eventually come out.

“This report not only confirms that brands are making a greater commitment to interactive, but also points to the fact that mobile and digital video are being identified as integral elements of the marketing mix,” said David Silverman, a partner at PwC US, which prepared the IAB’s report. “Internet advertising’s ability to impact and engage is evident across digital screens, whether big or small.”

“Consumers are embracing new screens, new content and transforming how they shop, communicate and consume content at an accelerated clip,” said Sherrill Mane, Senior Vice President, Research, Analytics and Measurement at the IAB. “And, in response, marketers are turning to those same interactive arenas just as quickly.”
