Audience reach refers to the total number of unique viewers or listeners that a television program or media content can potentially engage over a specified period. This metric is crucial for understanding how widely a show is disseminated and the potential impact it can have on advertising revenue, audience engagement, and program popularity. A higher audience reach indicates a greater ability to connect with diverse demographics, which is especially important in the context of syndication, where programs are broadcasted across multiple platforms and networks to maximize viewership.
