Who said this?
Why the bible itself...Advertising Age!

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.
