A slide is a single page of a presentation. Collectively, a group of slides may be known as a slide deck. A slide show is an exposition of a series of slides or images in an electronic device or in a projection screen.
In the digital age, a slide most commonly refers to a single page developed using a presentation program such as Microsoft PowerPoint, Apple Keynote, Apache OpenOffice or LibreOffice. It is also possible to create them with a document markup language, for instance with the LaTeX class Beamer.
Slide producing software
Presentation slides can be created in many pieces of software such as Microsoft PowerPoint, Apple Keynote, LibreOffice Impress, Prezi, ClearSlide, Powtoon, GoAnimate, Snagit, Camtasia, CamStudio, SlideShare, and Reallusion.
- PowerPoint is currently the most popular slides presentation program. LibreOffice Impress is a FOSS alternative.
- Prezi was developed in 2009 by Peter Arvai, Peter Halácsy and Ádám Somlai-Fischer in Budapest and San Francisco. Today, Prezi has 40 million users internationally.
- Apple Keynote, updated for OS X El Capitan, works on Macs and some other Apple devices.
- ClearSlide is commonly used in marketing and sales organizations for presentations to customers.
- Google Slides was developed by Google at the same time as Google Docs and Sheets, in 2007. The tool allows live collaboration.
Typically in a set of slides (a "deck"), all the slides will have a similar layout template, controlling such factors as margins and headings.
Slide sharing websites
Some websites offer facilities to share slide presentations online.
Selection of slide sharing websites
Another way of sharing slides is by turning them into a video. PowerPoint allows users to export a presentation to video (.mp4 or .wmv).
