# Delay and Stray

## Delay and Stray

**Delay and stray** is the specific failure mode attached to [[concept-ad-timing-choice]]. It occurs when a viewer is given the option to defer an advertisement to later in the session, but then abandons the content entirely *before* the scheduled ad ever plays. The impression is lost.

**Who is at risk.** The authors note the risk is highest among **uncommitted users** — people on a free trial, or those sampling the first few minutes of an unfamiliar series to decide whether it is worth their time. For these viewers, offering timing choice hands them an easy way to defer an obligation they never return to fulfill.

**Strategic response.** Because the risk tracks commitment level, the mitigation is user segmentation:
- For low-commitment users, do *not* offer timing choice — force a pre-roll ad or offer content choice instead (see [[action-mitigate-delay-stray]]).
- For high-commitment users (binge-watchers, long-time subscribers), the abandonment risk is low, so timing choice is a safe way to grant autonomy (see [[action-timing-for-binge-watchers]]).

This segmentation logic is the backbone of [[framework-ad-control-deployment]].

**Enrichment note:** The label 'delay and stray' appears to be the authors' own term of art; no other study uses it. The underlying phenomenon, however, is consistent with well-documented drop-off behavior around streaming ad breaks and with the industry practice of favoring pre-roll placements for short or uncertain sessions to minimize non-delivery risk.
