The Associated Press (AP) announced today that 728 AP newspapers have joined its Mobile News Network. The service was first launched in May of this year, and the additions account for a 580% jump in media participation. If you want to be a well informed citizen of the world on-the-go, AP Mobile News Network is a must. This application will give you breaking news, sports, entertainment, politics, business and wacky content in the palm of your hand.

“It is an exciting time for the Mobile News Network as we realize our goal of becoming the news portal for mobile devices,” said Jeffrey Litvack, AP global director for new media markets. “With over 700 news content providers, the Mobile News Network is now the first national footprint for local news on the mobile phone. Leveraging this network, marketers can build integrated campaigns at the neighborhood level both in mobile and print, and mobile users can access their local trusted sources of information wherever and whenever they want.”
