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 its viewership by including less niche programming. Often, this results in a shift from informative or artistic quality programming aimed at cultured and educated viewers toward sensational, ratings-based or reality-formatted programming designed solely for the entertainment of a mass audience. Channel drift frequently features the incorporation of infotainment, reality television and heavy advertising into the channel's lineup.
