AdSense usage by industry

[sunday silence]

Does anyone have any reference to which industries spend the most money on adsense ads? A quick google search produces nothing but basic information on how to use adsense, etc.

Which industries get the most out putting money into adsense? hi tech? media? lawyers? Anyone have any hard numbers?

You might want to search for Adwords, not Adsense.

Adsense is the publisher product, not the advertiser product, and accounts for only part of the total Adwords dollars.
