RESEARCH : When Do Trailers Appear?

Trailers are commonly released during a window that would best maximise sales for that film, for example a seasonal film such as a Christmas film would be released during the Christmas season, leading to more sales as people are looking for that kind of film during that period.

Distributors would keep track of their competitors film's release scheduled to make sure that they don't release films during the same window as them, this is done to maximise sales and make profits as large as they possibly can. Therefore that would mean that their trailers would be posted during a time where there is limited competition to gain public knowledge and interest before their competitors have a chance to do the same.

                           

They look for when the best weekend would be to start screening, this is because films earn most of their money throughout their theatrical run during their opening weekend, so if it failed then they would have to withdraw the film.

Distributors must also consider holding the film back and not have multiple screenings in one day this is primarily done to sell out their screenings and will allow the distributor to argue that the film deserves more screenings as the demand for the film has increased and be able to convince cinemas to keep it playing as long as possible.
