Toy Story 3 - Official Teaser Trailer

This is an example of a  teaser trailer that has come out. The characteristics of the teaser trailer are that it is short and doesn't give away any of the storyline and that you only know that something is going to be coming out with that name and the different characters involved. This builds up the anticipation by the audience and makes them want to go and see it more because they have been left on a cliffhanger.
