The degree to which an avid viewer of a TV show, cartoon, or internet series notices a slight change in style or content over an extended period of time is called "series drift". Often times, series drift is responsible for the waning of the popularity of such a program. Occasionally, series drift can have a positive affect in attracting a larger audience. In cases when series drift has a strong negative affect, the producers of the program in question may resort to jumping the shark.
