Radio One (ROIA) unveiled three separate deals Monday to acquire 22 radio stations.

With the deals announced Monday, Lanham, Md.-based Radio One, which operates more than two dozen radio stations serving primarily African-American listeners in such top urban markets as Atlanta, Baltimore, Philadelphia, Detroit, and Washington, DC, added stations in big markets such as Los Angeles, Houston and Dallas.

The centerpiece to Monday's announcements is a $1.3 billion agreement to buy from

12 radio stations in seven of the largest U.S. markets. Clear Channel has inked several agreements in the last week to divest a boatload of stations because of its pending merger with AMFM, a deal that will create the biggest radio station operator in the country.

Radio One also announced a deal with closely held

and

to acquire three stations in Indianapolis for $40 million in cash and stock. Radio One also entered the Charlotte, N.C., and Augusta, Ga., markets with its $24 million deal to acquire
