Radio host and renowned social activist Joe Madison, also known as "The Black Eagle," has joined XM Satellite Radio's in-house team.

On June 2nd, Madison will start broadcasting live each weekday from XM's Washington, DC studios from 6am - 10am ET on The Power (ch 169). The Power is the only national radio channel dedicated to African-American talk programming.

Joe Madison is no stranger to XM. He historically had done his show from WOL/Radio One studios in DC for 10-years, where his show was simulcast on XM. Talks between XM and Radio One to continue that arrangement are in the very early stages.

"The addition of Joe Madison to our in-house team underpins XM's commitment to outstanding African-American talk programming," said Nate Davis, CEO and President of XM. "The Black Eagle delivers for his listeners everyday. His engaging style is driven by his unmatched curiosity and awareness of the key civil rights issues around the world."

Madison was named one of Talker Magazine's 100 Most Important Radio Talk Show Hosts nine times and is widely regarded as the nation's leading African-American activist talk radio host. Madison's commitment to social activism has also resulted in his incarceration for civil disobedience, hunger strikes in opposition to apartheid in South Africa and the genocide and slavery occurring in modern-day Sudan.
