AUDIENCE MIGRATION INFORMATION

摘要

Event records can include session data representing a particular consumer and a particular standard period of time, and can include station identification information indicating a media station to which the consumer was tuned during standard period of time. Records can be designated as overlapping event records if multiple event records represent the same consumer and the same period of time, but identify different media stations, and at least some overlapping event records can be eliminated from consideration before determining audience migration information. Audience migration information, including tune-ins and tune-outs, can be determined based on whether or not a consumer has multiple event records showing different media stations at adjacent times. The audience migration information can then be transmitted to an end-user machine for display.

1. A method comprising:
obtaining from an audience data provider, at a server machine, a plurality of event records, wherein each of the plurality of event records includes session data representing exactly one consumer and exactly one standard period of time, and wherein each event record includes station identification information indicating a media station to which the exactly one consumer was tuned during at least a portion of the exactly one standard period of time; identifying, at the server machine, overlapping event records, wherein an event record is designated as an overlapping event record if multiple event records represent a same consumer and a same standard period of time, but different media stations; eliminating from consideration at least some overlapping event records before determining audience migration information; determining the audience migration information, including determining a number of consumer tune-ins and tune-outs, wherein:
a consumer tune-in occurs when a given consumer is represented by an event record for a first station during a first standard period of time, but the given consumer is not represented by an event record for the first station during a second standard period of time immediately prior to the first standard period of time;a consumer tune-out occurs when a given consumer is represented by an event record for the first station during the first standard period of time, but the given consumer is not represented by an event record for the first station during a third standard period of time immediately subsequent to the first standard period of time; and transmitting the audience migration information from the server machine to an end-user machine, the end-user machine configured to display a graphical representation of at least a portion of the audience migration information.
