funny stats

15. 445 different advertisers delivered more than a billion banner ads in 2012. (ComScore)

interesting...1/5th of all banners were for the 445 top advertisers...

would be interesting to see the ratios mobile vs. computer segmented...

advertising needs to change something in core

That being said, a large portion of the inventory is for branding purposes, if you can display the same message to your target segment multiple times a day, some of that message will inevitably get stuck in the brain. The resulting action does not have to take place on the web but at the POS.

Same goes for retargeting networks, networks like criteo pay quite a high CPM to be put in first place on the cascade.
