Other key facts:
> Surprisingly, the company is seeing little change in the cost of impressions or the visibility of its ads on the internet, she said. An impression is generally counted each time an ad is shown.
I take that to mean that the tail didn't cost very much, and didn't increase ad visibility very much.
