A magnification system includes a display device configured to receive and process input from a viewer to magnify portions of a displayed ad or image. The magnification system includes various magnification applications including a use magnifier and scrolling magnifier applications. The use magnifier produces a moveable window that is placed over a portion of the displayed ad or image to magnify without distortion in the moveable window that portion of the ad or image over which the window is located. The use magnifier is always available in the magnification system without activation. The scrolling magnifiers include column magnifiers and row magnifiers that may adjust the position of the ad or image on the display screen and produce a scrolling window that moves across a portion of the adjusted ad or image to magnify without distortion that portion of the adjusted ad or image over which the scrolling window is currently located.
