A slide show is a series of pictures or pages of information, often displayed on a large screen using a video projector. The first slide shows were done with pictures on pieces of glass, to be later replaced photographic film slides in the 1940s. As the technology improved, overhead projectors began to be used to project a picture on a screen and the slides were made with transparent slide media, about the size of a piece of paper. Printers could print text and images on this media or dry-erase markers could be used to write and draw on the media.
