Dayparting

In broadcasting, dayparting is the practice of dividing the day into several parts, during each of which a different type of radio programming or television programming apropos for that time is aired. Programs are most often geared toward a particular demographic, and what the target audience typically engages in at that time.

For example, rush hours are often particular dayparts for radio stations. Traffic reports are usually given at these times, and rarely at others. On TV, mornings are often filled with children's programming (especially on weekends), while late-nights are attractive mostly to young adults.
