Film trailers have been shown in various different techniques such as, T.V and cinema are the most popular places which show film trailers because it reaches wide audiences, now online streaming sites are taking over and most distributors want to use these sites because the amount of users on them is rising fast, these can be Netflix, Amazon Prime and Now TV, a very popular site where film trailers are shown is YouTube, YouTube has such a large audience film trailers are frequently shown because it spreads across the world, although film trailers which are over 30 seconds generally get skipped, people want to watch the video they selected not a 3 minute trailer unless it appeals to them. I personally watch the first minute of a film trailer to see if it is interesting and if it is I will continue to watch it otherwise i'll skip it. The trailers shown on YouTube becomes repetitive so more people begin to skip the trailers making it harder for the films to become recognised.
The advantages of using these different sites is that the trailers are shown in most places in the world, it spreads everywhere so everybody who is interested in the film can see more about it, the wider the audience it gets out too the more money the business makes because more people are going to want to see the film. The disadvantages of this are that many of the websites offer to skip the advert to you can easily miss the trailer, also using online websites many countries don't have access to the web so they won't be able to watch these trailers either.
When people watch TV they do not usually concentrate during the adverts. I would agree with this statement because when adverts are playing after an episode and the next one is due 5 minutes after and adverts play, its a chance to have a break and say get a drink or food, so I personally don't pay attention to the adverts because I would sit on my phone whilst adverts play because I find them boring and repetitive.
Lots of people stay at home to watch movies rather then go the cinema because over recent years movies are becoming available on TV not long after releases of films in the cinema, it is also cheaper to rent the film and can be cheaper to buy and keep, so people don't have to leave home to watch their favourite movies, this can be a disadvantage because in the cinema it shows all of the new trailers which will be coming later in the year and you are to a certain extent force to watch it whereas at home you can ignore these trailers and say have a break from TV.
DVD's are watched over and over again so when viewed you can skip all of the trailers because the viewers want to watch the film they bought instead of sitting through 15 minutes of trailers. Although DVD's are a great way to show trailers because the first 10-15 minutes are trailers and the viewer may watch them all once then the film, they will skip the net time but the DVD has done its job in getting the trailer across to a wide audience.
Posting links to film trailers doesn't always significantly boost viewing figures due to the amount of false links on websites now, it is now risky when clicking on links because you can't trust links because of the amount of online scammers and people posing as false promotions, although if it is a link to a trailer then this can boost views because a lot of people use the internet but its trusting whether or not the link is a scam and most people want to be on the safe side and not click on dodgy links.
Trailers who are certified for ages 18 and above which are cut down because it can be seen as offensive to those who are under the certified age, can be dissatisfying for older audiences because they want to watch the whole trailer and would like to know as much about the film as they can. A good example is Deadpool, it originally was an 18 but was then modified to be suitable for a 15 and above, this was seen as dissatisfying to older audiences because everyone knows that Deadpool is a rude and offence film which is also very funny and older audiences want to see the full un-modified version of Deadpool to gain the full experience of the film.
