Microsoft CEO Steve Ballmer has attacked Google's business model, claiming that reading customers' email doesn't work.
Ballmer, who was speaking to an audience in the UK, claims making money from email services is very difficult.
"Our Windows Live Hotmail doesn't generate much ad revenue, so we've had to put a portal around it, because the traffic it brings is very valuable, but it's not very easily monetised," he claims.
He then launched an attack on Google, claiming its business model of selling advertising based around the content of email is flawed. "Google's had the same experience, even though it reads your email and we don't."
