In modern times the use of personal computer screen savers has changed with the advent of liquid crystal (LCD) and light emitting diode (LED) displays. Back in the day, however, in the early develoment of personal computing, the display screen technology used would literally burn an image of what’s on your screen into the screen itself if the image stayed constant for too long. This phosphor burn-in of, particularly, cathode ray tube (CRT) screens resulted in the advent of the screen saver industry.
By providing a constantly moving image for your CRT screen when not in direct use, screen savers prevented phosphor burn-in and extended the life of your then very expensive screen.
The creators of the screen saver industry are believed to be Bill Stewart and Ian MacDonald. The first screen saver product created by Stewart and MacDonald, named Magic Screensaver, is still available for 16-bit Windows format download on the website of Stewart’s company Dynamic Karma.During the beginning of the screen saver industry the practical reason for its existence was the main foundation of what appeared on your display. This is why many early screen savers used a black screen to prevent burn-in, including the Magic Screensaver.
As time went by creative computer programmers started using animations to make the screen saver’s appearance more interesting. One such innovative new-style screen saver was Flying Toasters in the After Dark series, created by Stewart and MacDonald’s Software Dynamics/Dynamic Karma/Berkeley Systems. (Some controversy exists regarding the original and current owners of the right to call themselves the creators of Flying Toasters, probably due to the huge commercial success of the product.)
Particularly popular with Mac users, this interstellar-warrior-like-outer-space flying toaster-with-toast moving image, featuring sound and animated on-screen captions, became the most famous of all screen savers.
Flying Toasters is hence credited with inspiring the launch of the popular modern screen saver style of interesting moving objects of any imaginable kind. The screen saver industry continues to develop new products for users today, even though they are not strictly necessary to prevent phosphor burn-in anymore.
It’s amazing how inspiring toasters and toast can be!
