Captions move from 'nice to have' to 'expected'
Five years ago, captioning a conference was a budget line you defended. Today, accessibility coordinators, corporate sponsors, and your largest attendees expect it as table stakes. The events that don't caption look stale. The events that caption only the keynote look like they're going through the motions.
Per-event pricing makes blanket-captioning the entire program feasible. The marginal cost of adding captions to a sixth, seventh, or twelfth concurrent room is near zero. That's the threshold above which your accessibility statement matches reality.
