Curiosity needs an executable action
Online discussion becomes a transaction only when people can find a session, accept the price and spend the time. Added screenings shorten that distance and give curiosity a practical outlet.
For some viewers, the ticket is also admission to an online event. Laughter, ticket stubs and short reactions create new material for the feed.
The loop cannot run forever
Once most potential viewers know the contrast, the marginal value of curiosity falls. Longer attention then depends on story, emotion or ideas that survive the reveal.
The viral curve explains a turn, not endless growth. A responsible record keeps dates visible instead of treating peak velocity as a permanent condition.
