Apple will launch its iAd mobile advertising network in the United Kingdom and France in December, and in Germany in January, MediaGuardian reported today.

The service, which launched in the United States on July 1, displays targeted ads in iPhones and iPod Touches, letting users stay within their current app. According to Brand Republic, the European version includes advertising from Nespresso, Perrier, Turkish Airlines, L'Oreal and Absolute Radio, among others.

"In just four months, we've doubled the number of advertisers on the network and thousands of developers now have a valuable new source of revenue," Apple's vice president of iAd Andy Miller stated in a press release, claiming that users remained engage with the ads for an average of 60 seconds.

Miller also said the expansion would "create even more great opportunities for developers." The company, which hosts and sells the ads, allows third-party developers to keep 60 percent of the revenue they generate.

However, MediaGuardian reminded that "only two of the first 17 U.S. advertisers managed to use it for a campaign in the first month following launch, with just three more in August."
