We “Cut the Clutter” and Choose the Right Radio “Mix” for Your Message! Running a “fixed” radio schedule ensures listeners during “key” times like AM/PM Drive, Sports Programming, etc. Sponsorship allows a consistent “branding” message without the hassles of keeping your ad copy or messages up to date. ROS (run of station) schedules are effective and provide “frequency” as well as a lower cost per spot and works well for weekend flights and as “bonus” weight when negotiating. ROS is effective with a consistent, general or institutional message.
