TargetSpot has just inked an agreement with Entercom that empowers its advertisers to create, buy and place advertising on Entercom's network of radio stations, according to a recent press release.

This move is the second successful liaison by TargetSpot in its effort to build stronger ties to radio. The firm recently developed a relationship with CBS RADIO.

TargetSpot's technology enables advertisers to build customized audio, video, banner and text ads with a series of sound effects, ditties and visuals.

The Entercom lattice consists of over 90 streaming radio stations.
