Apparatus and methods to estimate media audience consistency

A non-transitory computer readable storage medium comprising instructions which, when executed, cause one or more processors to at least:

• access media measurement data communicated via a network from a plurality of media monitors, the media measurement data corresponding to a plurality of panelists;
• determine a first number of the panelists exposed to a first quantity of a first broadcast;
• determine a second number of the panelists exposed to a second quantity of the first broadcast;
• output a consistency metric associated with the first broadcast, the consistency metric based on a variation of at least the first number and the second number;
• and
• adjust an advertising schedule based on the consistency metric, the adjustment of the advertising schedule to at least switch a first advertisement previously scheduled to be presented at a first time with a second advertisement different than the first advertisement.

A method comprising:

• accessing, by executing an instruction with a processor, media measurement data communicated via a network from a plurality of media monitors, the media measurement data corresponding to a plurality of panelists;
• determining, by executing an instruction with the processor, a first number of the panelists exposed to a first quantity of a first broadcast;
• determining, by executing an instruction with the processor, a second number of the panelists exposed to a second quantity of the first broadcast;
• outputting, by executing an instruction with the processor, a consistency metric associated with the first broadcast, the consistency metric based on a variation of at least the first number and the second number;
• and
• adjusting, by executing an instruction with the processor, an advertising schedule based on the consistency metric, the adjusting of the advertising schedule including changing a first advertisement previously scheduled to be presented at a first time with a second advertisement different than the first advertisement.
