Can Google sell that radio gaga?

If there was any doubt about the scope of Google’s ambitions in the off-line advertising world, one of its recent job postings should dispel them. It seeks a "head of national TV sales" to help build "a world-class national TV advertising sales team."

Then there is radio. The chief executive of Google, Eric Schmidt, said last year that the company would eventually have 1,000 employees dedicated to radio advertising alone.
