Here are some great pull-quotes from the article.

"In this recession, marketers have learned that interactive marketing is more effective, and advertising less effective, per dollar spent. While budgets for online have decreased, they decreased less than other budgets. Six out of ten marketers we surveyed agreed with the statement "we will increase budget for interactive by shifting money away from traditional marketing.  Only 7% said we have no plans to increase our marketing budget."

"Unlike the last recession, digital marketing is no longer experimental. Now it looks more like advertising is inefficient, relative to digital. More than half of the marketers we surveyed said that effectiveness of direct mail, TV, magazines, outdoor, newspapers, and radio would stay the same or decrease within three years. In contrast, well over 70% expected the effectiveness of channels like created social media, online video, and mobile marketing to increase. The result is that digital, which will be about 12% of overall advertising spend in 2009, is likely to grow to about 21% in five years. Along the way overall advertising budgets won't grow much. This is huge."
