Inheritance effects, especially high levels of audience duplication between adjacent programs, are a widely observed but little understood feature of audience behavior. This study places inheritance effects within a theoretical model of television program choice that attributes the general phenomenon to underlying patterns of audience availability. The absolute level of audience duplication between adjacent programs broadcast on the same network is determined by the rating of each program, the structure of available program options, and similarities in program type.
