For many years, movie theaters have been using projectors to show movies.  This was true long before digital projectors, but these newer projectors have been adopted for the same purpose.  They are much simpler to use, require far less space, and can be less expensive over-all.  Theaters use these projectors to display on indoor and outdoor screens alike.<br />

Some people also use digital projectors for private entertainment systems.  For reasons such as display size and device size, some are willing to pay the extra expense of a digital projector for personal use.  As the technology improves, so does the output resolution as well--many modern projectors offer at least an HD 1080p display.<ref>http://www.projectorreviews.com/projector-categories/digital-projectors</ref><br />

Many churches and chapels also use projectors.  In some cases, they are used to display slideshows or other visual material while the pastor or minister is speaking.  In other cases, they are used to show the lyrics to a song or hymn so that the congregation may sing along.
