This chart is mind-blowing. How, in the year 2008 (when this analysis was done) can marketers still be so far behind on where their audience is? It's not 1998 anymore.
Here's what else is interesting: Google (and a number of online advertisers) has made a killing despite the low investment from marketing in this area. Imagine what happens when marketers do get with the times. Or, what happens when companies realize they can reach more of their audience with less dollars and that their ROI is higher online than TV (have they not realized that yet)?
Or maybe they never learn. Sigh.
