Presentation program is a software package used to display information in the form of slide shows. It has three main functions: an editor that allows text to be inserted and formatted, methods for inserting and manipulating graphic images, and slide-show systems for displaying content.

Histori
Initial graphical presentation software runs on computer workstations, such as those produced by Trollman, Genigraphics, Autographix, and Dicomed. It becomes very easy to make last minute changes compared to traditional lettering and copying settings. It's also much easier to generate a large number of slides in a short time. However, these workstations also require skilled operators, and one workstation represents an investment of $ 50,000 to $ 200,000 (in 1979 dollars).
In the mid-1980s developments in the computer world changed the way presentations were made. Inexpensive, special applications now make it possible for anyone with a PC to create professional-looking presentation graphics.
Initially these programs were used to produce 35 mm slides, to be presented using a slide projector. As these programs became more common in the late 1980s, some companies created services that would accept performances on floppy disks and create slides using movie recorders or transparency printing. In the 1990s a special LCD-based screen that could be placed on the projector began to replace transparency, and by the late 1990s almost everything had been replaced by a video projector.
The first commercial computer software specifically aimed at creating a WYSIWYG presentation was developed at Hewlett Packard in 1979 and called BRUNO and then HP-Draw. The first software that featured presentations on personal computer screens was VCN ExecuVision, developed in 1982. The program allows users to choose from an image library to accompany their presentation text.

Features
A presentation program should help both speakers with easier access to their ideas and participants with visual information that complements the conversation. There are many different types of presentations including professional (work related), education, entertainment, and for general communication. Presentation programs can complement or replace the use of old visual aid technologies, such as pamphlets, flyers, whiteboards, flip charts, posters, slides and overhead transparencies. Text, graphics, film, and other objects are positioned on individual pages or "slides" or "foils". The "slide" analogy is a reference to a slide projector, a device that has become somewhat obsolete due to the use of presentation software. Slides can be printed, or (more often) displayed on the screen and navigated through at the presenter's command. All presentations can be saved in video format. The slide can also be saved as an image from any image file format for any future reference. The transition between slides can be animated in various ways, such as the appearance of elements on the slide itself. Usually the presentation has many constraints and the most important is the limited time to present consistent information.
Many presentation programs come with pre-designed images (clip art) and/or have the ability to import graphic images, such as Visio and Edraw Max. Some tools also have the ability to search and import images from Flickr or Google directly from the tool. Special graphics can also be created in other programs such as Adobe Photoshop or Adobe Illustrator and then exported. The concept of clip art originated with an image library that came as a complement to VCN ExecuVision, beginning in 1983.
With the growth of digital and video photography, many programs that handle this type of media also include presentation functions to display them in a similar "slide show" format. For example, Apple's iPhoto allows groups of digital photos to be displayed in a slide show with options such as selecting transitions, choosing whether the event stops at the end or keeps playing, and includes music to accompany the photo.
Similar to programming extensions for operating systems or web browsers, "add ons" or plugins for presentation programs can be used to improve their capabilities. For example, it would be useful to export a PowerPoint presentation as a Flash animation or PDF document. This will make sending through removable media or sharing over the Internet easier. Because PDF files are designed to be shared regardless of platform and most web browsers already have plugins to view Flash files, this format will allow presentations to be more widely accessible.
Certain presentation programs also offer interactive integrated hardware elements designed to engage an audience (eg audience response system, second-screen app) or facilitate presentations in different geographic locations via the Internet (eg web conferences). The other integrated hardware facilitates the work of a live presenter such as a laser pointer and an interactive whiteboard.
