Final answer:
The statement refers to a Born Active Viewer (BAV) as an active viewer who completes at least one five-minute play, which suggests a metric for measuring audience engagement, but without a universal definition it cannot be designated as true or false definitively.
Step-by-step explanation:
The question posed appears to be referencing a definition or metric used in the context of audience analysis or digital analytics, possibly specific to an online platform or service. However, without a standardized or widely recognized definition, it's challenging to definitively determine if the statement "Born Active Viewer (BAV) - Born viewer that completes at least one five-minute play." is categorically true or false. Typically, the concept of an active viewer in digital analytics would suggest a user who not only starts but also completes an engagement with a video or content, implying they have a certain level of interest or interaction with the content provided.
