Information:  - Sister shows are two or more television shows which exist in the same fictional universe and which may have crossovers. They differ to a degree from spin-offs in that shows may air simultaneously, rather than being derived from, and replacing, another. The popularity of most shows is limited to a few seasons, and sister shows allow expanding the immediate audience and ratings share. This is accomplished by using mostly different actors and production facilities. Sister shows often shift styles or target audience slightly, for a larger overall market. Thus "The Beverly Hillbillies" emphasizes slapstick, while "Green Acres" emphasizes surreal humor.  - Drama is the specific mode of fiction represented in performance.
