In radio and television, segments of the broadcast day.

A set of statistics about a person or group of people. Demographic information may include age, sex, maritual status, ethnic background, occupation, religion, household income, household size and other factual information.

(Radio) The time segments into which a day is divided by Radio stations for the purpose of selling advertising time.
In Radio, the main dayparts are morning (or AM drive), midday, afternoon (or PM drive) and evening.
An individual station's daypart(s) will not necessarily conform to standard definition(s). Advertising contracts should include the specific hours that define the time period for each station?s daypart.

The relative importance of one time period compared to another in a schedule that includes both, usually expressed as a percentage where the total of all dayparts equals 100%.
Also refers to the relative distribution of commercials in one time period versus others in the schedule.

(also known as ?Midday?): The late morning/early afternoon broadcast time period for Radio, most often represented by Monday though Friday from 10AM-3PM as defined and reported by Arbitron.
Since an individual station's daypart(s) will not necessarily conform to standard definition(s), and since traffic departments use the term ?daytime? to refer to a broader 6AM- 7PM time period, all advertising contracts should include the specific hours that define the time period for each station?s daypart.

(DMA): DMA is the main geography for television measurement.
The DMA is composed of sampling units (counties or geographically split counties) and is defined and updated annually by Nielsen Media Research, based on historical television viewing patterns. A county or split county is assigned exclusively to one DMA.

A backlit display located in airports, bus terminals and sports stadiums/ arenas.

Data about the size and characteristics of a population or audience such as gender, age, income band, personal preferences etc.
