The ownership of the studio may have an impact on what films the studio makes because the ownership decides what gets published by them, and only publishes what they prefer. So that means the decide what the studio does in order for it to be published.

Films are promoted in different ways to target different audiences like in forum discussions, newsletters, Facebook pages, fan clubs & sites etc.

Distribution
Distribution is sharing things out among people.
after the editing stage, they promote the film by using posters, trailers etc. then rent out cinemas all over the area for a certain period of time.
film distributors distributes films and producers sometimes some times does it and sometimes it’s the company who owns them instead.
the traditional way of distributing film is through tv trailers
A film festival is an organised, extended presentation of films in one or more cinemas or screening venues, usually in a single city or region. Increasingly, film festivals show some films outdoors. This helps to promote films, and make them more money.
Distribution is essential to the film chain because if a film is made and is not distributed, then that means its not available for citizens to view or even know about. If a film can't secure a distribution deal, then most probably it won’t be able to go to cinema, and will not make any money at all.
Marketing
the action or business of promoting and selling products or services, including market research and advertising.


exhibition
These days, we get to see films by cinema, online streaming, TV, netflix/lovefilm, mobile phones, blu-ray, dvd player, projectors etc.
A box office is a place where tickets are sold to the public for admission to an event. Patrons may perform the transaction at a countertop, through an unblocked hole through a wall or window, or at a wicket.
In a successful film, the people who receive the earnings are; producers, directors, actors and distributors.
Cinema makes their money by tickets, concessions, onscreen advertisements, and costs.
Cinema encourages the audience to visit the cinema instead of watching it at home by providing ticket concessions, 3D movies and offers.
Ancillary markets are films not shown in cinema, like home video, television, Pay Per View, VOD, Internet streaming, airlines and others.
This enables the exhibition of film because its still being watched outside of cinemas.
BFI means British film industry, and they are required to use the lottery fund to support film development, production and distribution in the UK. This helps films become published and be successful in the UK and many parts of the world.
