Network decay

Channel drift or network decay is the gradual shift of a television network away from its original programming, to either target a newer and more profitable audience, or to broaden their viewership by including less niche programming. Often, this results in a shift from informative, quality programming aimed at the high culture and educated viewers, toward sensational, ratings-based, and/or reality-TV programming designed solely for the entertainment of a mass audience. Channel drift frequently features the incorporation of infotainment, reality television, and/or heavy advertising into the channel's lineup.
