NEW YORK: Online advertising firm DoubleClick is reportedly in sale talks with Microsoft. Its current owner is a San Francisco private equity firm that bought it for $1.1 billion (€824m; £560m) in 2005.

Since then, Hellman & Friedman has sold off a number of divisions and restructured the business. It is now said to be looking for a $2bn-plus deal from a number of suitors.

DoubleClick manages, delivers and measures online advertising, business which reportedly brought in around $150m in revenue last year.

A company spokeswoman was resolutely zip-lipped about "rumors and speculation".
