Broadcasting company Radio One has struck a deal to sell ads on hip-hop news site AllHipHop.com.

The agreement spans five years and gives Interactive One, Radio One's digital division, exclusive access to AllHipHop's ad inventory. AllHipHop boasts five million monthly users.

Advertisers running ads on AllHipHop will also have access to Radio One's system, availing opportunities to broaden the reach of their messages as Radio One expands the breadth of its ad network reach.

Radio One has made a number of recent moves to increase its African-American audience. Last month it bought social network operator Community Connect and launched NewsOne.com, an African-American news site.
