Depending on the context, films are also known as movies, motion pictures, videos or documentaries. The term “film” was adopted because motion pictures were originally shot using reels of photographic film. By projecting a series of still images shot in quick succession, it is possible to create the illusion of movement. A typical film is shot at 24 frames per second. Although many films are now made using digital technology, the term “film” endures. In the business world, a company may make films to advertise its products or services, as a means of publishing interviews with employees or management, or to record events at a trade fair or conference.
