Pandora Local Market Analysis By Edison Research: Methodology

By Tom Webster

Definitions

Listeners
Only registered users are counted. Registered users are Pandora users who have created an account, providing their age, gender, zip code and email address. Pandora One subscribers or listeners who are not registered (anonymous users) are not included in the analysis. In addition, no attempt is made to determine if more than one person is listening at a time.

Market Area
This analysis used publicly available Metro Survey Area (MSA) definitions, as defined by Arbitron. Listeners were coded into a MSA based on their current zip code information.

Audience Measurements

Average Quarter Hour
In order to qualify as having listened, a listener must have listened for at least five minutes during a quarter hour. Listening does not need to be contiguous during a quarter hour. Time is measured in seconds.

In cases where a listener skips, pauses, changes stations or leaves Pandora before a song completes, the actual time listened prior to the action is counted and not the entire song length. When listening to a song crosses into a subsequent quarter hour, each quarter hour is credited with its share of time.

Any qualifying quarter hour is included in the average quarter hour calculation (AQH).

Cume
Any listener listening to at least one quarter-hour within a time period is counted as a distinct listener (Cume).
