Subliminal ads coming to a PC near you?

Students were exposed to either Apple or IBM's logo for 30 milliseconds

Conventional advertising techniques work for some companies but, for many others, getting their products in front of the right customers is tough. To this end, Duke University has conducted a study to find out what form of advertising works best.

Researchers asked students to watch a screen and chart the appearance of a multicoloured box in different places on the display, keeping a running tally of numbers appearing in the centre of the screen. During that time, the students were exposed to either Apple of IBM's logo for 30 milliseconds.
