Yahoo! announced the launch Monday of Yahoo! Sports Radio as the Internet company seeks to turn its popularity as an online destination for sports fans into success over the airwaves. The Sunnyvale, California-based Yahoo! said the national sports radio network will be available on over 180 affiliate radio stations across the United States, Sirius Satellite Radio, and through digital and mobile partners. The network is being launched in partnership with Houston, Texas-based Gow Broadcasting, whose Sporting News Radio stations are being rebranded as Yahoo! Sports Radio. "Yahoo!

"Our partnership with Gow Broadcasting will provide more access to our users and solutions to our advertising partners that want to connect with them wherever they consume sports," Fuchs said. Yahoo!
