Google another "Revenue Stream" is questioned

I have already wrote about YouTube revelations from Google TV Chief:

"All it means, that day when you can sell tons of Ads in copyrighted material taken for nothing with broadcast quality will never come, YouTube means CAPEX, more CAPEX, and some more CAPEX: blades, electricity without any business model yet."

Now there is another blow from Radio ad market:

"CHAD AND RYAN STEELBERG, THE founders of an automated radio ad placement company purchased by Google in January 2006, have left the company."...
"Google bought dMarc for $102 million in cash plus the possibility of further payouts totaling up to $1.13 billion, if certain revenue targets were met. But last week, Valleywag.com, a blog covering Silicon Valley businesses, reported that a source close to dMarc said management and investors were unlikely to get more than $200 million under the terms of the deal."

Sales are not coming here...nothing apart from clicks was ever created at Google...or sorry here was it Overture?
