Nice work if you can get it: apparently, each day's worth of Android activations probably generates $10m in annual mobile advertising revenue for Google. Not the findings of our sums, but those of Oracle which is currently embroiled in copyright case with the search giant.
In papers seen by the court - which is decided on a Java-related patent infringement - Oracle came up with the figure but it's not fact, just what it believes and doesn't, crucially, say how it came about those numbers.
The FOSS Patents blog has tried to narrow it all down and reckons that it's probably come from an assumption that each Android user brings the Mountain View company about $14 a year. All very complicated - especially if maths isn't your strong point! (*raises hand*)
Oracle also reckons that Android helps push users onto Google+ though we can't help feeling this is wishful thinking on its (and probably Google's part) since compared to Facebook and Twitter, Google+ doesn't seem to be gaining as much foothold in day to day use.
We love a good court case though!
