The objective of advertising has always been to get inside people’s heads, but now BMW has found a way to do it whether we like it or not.

Working with the lighting company Profoto, the German giant put together an ad that burns the company’s logo into your mind. Near the end of the ad viewers were told to close their eyes and were surprised to find that they could see the letters BMW as if they were written on the back of their eyelids.

The commercial took advantage of what is known as the afterimage effect, the same optical illusion that makes an image of the sun appear in your eyes long after you’ve stopped looking at it.

Don’t expect to see the technique showing up in TV commercials anytime soon though. Using afterimage likely qualifies as subliminal advertising, which has been banned in Canada and the United States since the mid 1970s. The ban followed the use of flash frames (think “Fight Club”) in commercials to implant messages into viewers’ minds.
