Daypart definition
/What is a Daypart?
A daypart is a division of the broadcast day into segments. For example, a television broadcaster may separate its schedule into the morning, daytime, early fringe, prime time, late news, late fringe, and late night time slots. The type of content provided to audiences will vary, depending on the daypart within which they are scheduled. This concept is also applied to radio airings.
A broadcaster typically evaluates the net realizable value of programs and program licenses for impairment using a daypart methodology, whereby programs broadcast during a particular time period, such as prime time, are evaluated on an aggregate basis.
