+! Monitor Burn-in
+Old CRT monitors and early plasma screens used to suffer from burn-in; if the same image was displayed on the screen for a long time it would eventually become permanently burned into the phospor. Screensavers were invented so that the monitor would have a constantly changing image to display and thus be 'saved' from burn in. On newer CRT monitors and LCD displays burn-in is not a factor.
