Ringleader Digital, a third-party ad serving network for mobile devices, will help deliver ads on Local Solutions Network Inc.'s Local Wireless network.

Local Wireless is a mobile network of local media content. Its addition to Ringleader's ad network means more than 50 million extra impressions per month available to mobile advertisers, the company claims.

"Ringleader integrates online ad campaigns with mobile advertising and we will be selling LSN's ads across all LSN and affiliate sites," said Bob Walczak, CEO of Ringleader. "Because of our relationship with LSN, our growing list of premium brands can leverage some of the most desirable ad inventory in local advertising."

Users on LSN's Local Wireless network can access news, streaming video, weather, finance and sports on their mobile devices.

LSN works with television stations and broadcast groups to deliver local content to mobile users across all U.S. wireless carriers. It has a network of local media news content in both English and Spanish, offering news, weather, sports and more in over 140 local market affiliates across the country.

Ringleader's network includes clients such as Best Western and Absolut. The company works with publishers, carriers and advertising agencies to take the online advertising experience to mobile.

The Ringleader network is device-agnostic and delivers ads by device functionality. This means that Ringleader can deliver ads on any available carrier network and distribute ads that work best with an end-user's device.

"Advertisers benefit because they can target very closely both on-deck and off," Mr. Walczak said.
