This helps put things in prospective.
Something to ponder, Apple asks $15billion this year for Google to be it's search engine on iphone. That's a 20% royalty rate if search ads generate $75billion this year on the iphone. Drugs pending approval have a 19% average royalty rate. Google search ads did $35billion last quarter maybe this year $150billion of the total $250 billion Google sales. If we do 4 to 5% of this in a royalty, that's $6billion to $8billion. If Google does $500 billion search & youtube revenue in the future in a year a 4% cut is $20billion, this seems fair. If Google is worth even 5X more in 10 years that's fair.
