iono.fm

iono.fm delivers dynamic audio ad insertion into podcast and radio-stream content, alongside podcast hosting, radio streaming for commercial and community stations, a themed mobile app, song and ad recognition in live streams and stream archiving to the cloud. Advertising is sold on a per-listen basis with low minimum ad buys, contrasted in the site's own text with traditional radio, where advertisers pay for broadcast time instead.

The site carries an Audio advertisement ad spot, and describes reporting that tracks where and how audio is listened to, with campaigns able to combine audio advertising across content partners ranging from national and regional to small community radio stations.
