XM Satellite Radio signed a three-year $55 million deal with Oprah Winfrey to host a talk show. “Oprah And Friends” is scheduled to launch next September on the top U.S. subscription radio service. XM’s smaller rival in the U.S. satellite radio market, Sirius Satellite Radio has already inked a number of high-profile deals, most notably a five-year contract worth $500 million with shock jock Howard Stern. XM also has exclusive deals with Major League Baseball, the National Hockey League and PGA Golf.
