# Ad Timing Choice

## Ad Timing Choice

**Ad timing choice** is the authors' proposed alternative to content choice: viewers decide *when*, during a viewing session, they will be interrupted by an ad, rather than *what* ad they will see.

**The headline finding.** Timing choice performs *just as well* as [[concept-ad-content-choice]] across the key metrics — visual attention, annoyance reduction, and brand recall. The effect sizes are statistically indistinguishable (see [[claim-timing-content-equivalence]]). This overturns the industry's assumption that ad *relevance* is the primary driver of engagement (see [[contrarian-timing-vs-content]]).

**Why it works without deep inventory.** Timing choice bypasses the [[concept-cognitive-burden-of-choice]] because it does not require the viewer to evaluate unfamiliar brands. It relies instead on something the viewer already knows well — their own schedule and attentional state. It therefore needs only *one* ad to function, making it robust when relevant inventory is thin.

**The distinct risk.** Timing choice introduces its own failure mode: [[concept-delay-and-stray]]. When users can defer an ad, low-commitment viewers may abandon the content before the deferred ad ever plays, producing lost impressions. Mitigation and segmentation are covered in [[action-mitigate-delay-stray]] and [[framework-ad-control-deployment]].

**Definition:** An advertising mechanism that allows viewers to decide the specific moment or phase during a viewing session when an advertisement will play.
