Run of Schedule (ROS) advertising refers to a type of advertising schedule in which commercial spots are aired at various times throughout the broadcast schedule, determined at the discretion of the radio or television station. This flexibility allows broadcasters to fill unsold inventory while offering advertisers a cost-effective option for reaching a broad audience.
Key Characteristics of ROS Advertising
Flexible Placement
ROS advertising does not guarantee specific time slots. Instead, ads are placed in available slots, optimizing inventory usage for broadcasters. This can lead to diverse audience exposure at different times of day.
Cost-Effective Rates
Due to the non-specific timing of ad placements, ROS advertising tends to be more affordable compared to fixed-time slot advertising. Rates are constructed to reflect this uncertainty, making it an attractive option for advertisers with flexible campaign requirements.
Audience Reach
Although ROS ads do not target specific time slots, they benefit from reaching a varied audience across different times and programs. This can be advantageous for products or services appealing to a wide demographic.
Types of ROS Advertising
Television ROS
In television broadcasting, ROS ads are distributed across various shows, time slots, and days. This can include a broad range of programming from news and talk shows to sitcoms and sports events.
Radio ROS
For radio, ROS spots are aired throughout different times of the day, reaching listeners during morning commutes, midday listening, afternoon drives, and evening leisure times.
Special Considerations
Reach vs. Frequency
Advertisers considering ROS should weigh the benefits of broad reach against the lack of frequency control. While ads will air multiple times, they won’t specifically target peak times when a larger or specific audience might be tuning in.
Target Audience
Businesses should assess whether their target audience is likely to be reached effectively through the varied placement of ROS ads. For products with broad appeal, ROS can be highly effective, while niche markets might benefit more from targeted time slots.
Examples of ROS Advertising
Case Study: Local Retailer Marketing

National Campaigns
National campaigns, such as those by major brands, may use ROS to supplement targeted advertising efforts. This ensures broad visibility while keeping costs manageable.
Historical Context
Evolution of ROS
The concept of ROS has been integral to broadcasting since the early days of television and radio. Initially, it provided a solution for broadcasters to utilize unsold inventory efficiently. Over time, it evolved into a strategic tool for advertisers to maximize reach under budget constraints.
