The FM to AM non-duplication rule of 1979 increased the required separate programming to what percentage in markets as small as 20,000?

• A. 75%
• B. 50%
• C. 25%
• D. 100%

Answer: (A)

This item tests understanding of the FCC’s FM to AM non-duplication rule from 1979, which is about preventing an FM station from simply simulcasting its AM partner. In markets and conditions defined by the rule, a certain share of the FM station’s programming must be distinct from what the associated AM station broadcasts. Specifically, in markets as small as 20,000 people, the rule requires that at least 75% of the FM station’s programming be different from the AM station’s content. This pushes stations to offer genuinely separate programming on FM, promoting more variety and localism in radio.

Think of why 75% makes sense: it ensures a substantial amount of unique content on FM so listeners get a real difference rather than mostly duplicating AM. Lower thresholds like 50% or 25% would allow a lot of shared content, undermining the goal of diversification. A 100% requirement would be too strict and impractical for day-to-day operations, so 75% represents a meaningful, achievable balance.
