It doesn't surprise me that online ad revenue is down. In fact, I'm surprised it took this long to happen. Online ads are just like "TV" in the sense that as people become used to them, they also become accustomed to tuning them out and they don't generate the same amount of business that they used to. I cannot remember the last time I clicked on an online ad, and I'm sure I'm not alone. If that's the case, why would advertisers pay to run ads?
