How do trailers and teasers build anticipation?

Teaser, trailer and the gap between them

A teaser is usually short and aims mainly to announce that something exists and set a mood. A fuller trailer comes later and gives a clearer sense of the premise. The gap between them is planned so interest can build in stages rather than all at once.

What a trailer is designed to do

A trailer is a marketing object, not a neutral summary. It is edited to create a feeling and a reason to show up, which is why the finished work can differ in tone from its trailer. Reading a trailer as persuasion rather than description keeps expectations realistic.

Timing against the release

Campaigns often sequence a teaser, a main trailer and later materials to keep a title visible without exhausting the audience before it arrives. The spacing is a deliberate choice, and an unusually early or late push can signal how confident a release is.
