Movies, also known as films, are a type of visual communication which use moving pictures and sound to tell stories or inform (help people to learn). People in every part of the world watch movies as a type of entertainment, a way to have fun. For some people, fun movies can mean movies that make them laugh, while for others it can mean movies that make them cry, or feel afraid. Most movies are made so that they can be shown on big screens at movie theatres. After movies are shown on movie screens for a period of time (ranging from a few weeks to several months), movies are shown on pay television or cable television, and sold or rented on DVD disks or videocassette tapes, so that people can watch the movies at home. You can also download or stream movies. Later movies are shown on television stations.
The Simple English Wiktionary has a definition for: movie.
A movie camera or video camera takes pictures very quickly, usually at 24 or 25 pictures (frames) every second. When a movie projector, a computer, or a television shows the pictures at that rate, it looks like the things shown in the set of pictures are really moving. Sound is either recorded at the same time, or added later. The sounds in a movie usually include the sounds of people talking (which is called dialogue), music (which is called the “soundtrack”), and sound effects, the sounds of activities that are happening in the movie (such as doors opening or guns being fired). In the 20th century the camera used photographic film. The product is still often called a “film” even though there usually is no film.
