See also: Reach

CIMM DEFINITION: The total number of homes, Set-Top Boxes  or individuals, which can be expressed in thousands or as a percentage, who have viewed at least once within a specific program or period of time aggregated across time or across individual pieces of content. Accumulated Reach can sometimes be higher than the Cume audience because it is based on a long term audience estimate, not with base minute minimums.

NOTE – Common usage to date has had both Cume and Accumulated Reach as interchangeable. In both cases there can be a minimum tuning duration or not. (Source: TRA
