Several U.S. publishers have joined the Nokia Media Network, a mobile ad network that reaches millions of mobile consumers, the company announced in a press release Wednesday.

Fox News, A&E Network, Bio Channel, History and The Hollywood Reporter have joined other publishers, such as Reuters, CNet, Hearst, Agence-France Press, Unidad Editorial and AccuWeather, strengthening the ad network's reach in the United States.

Publishers are increasingly looking for ways to monetize their mobile offerings.

Larry Shapiro, executive vice president for mDisney, stated in the press release that his company was looking for “brand-safe, high-performance media and its ability to reach our target audience.”

Nokia launched the mobile ad network in February.
