CHICAGO (CBS) — If you thought advertisers had thought of just about every place they could to get their messages out, think again.

Now, if you’re washing your hands at a restroom sink at O’Hare International Airport, or if you need to touch up your hair or brush your teeth, you will be greeted by a video ad in the mirror.

The Chicago Tribune reports that over the next three months, 150 video-equipped mirrors, each measuring 40 inches, will be installed in restrooms at O’Hare, courtesy of a company called Mirrus.

Advertising will fill the mirrors when no one is standing in front of them, and one someone walks up, they will shrink and move to a corner.

A sensor records how many people stand in front of the sink and for how long.

Of course, advertising in public restrooms is nothing new. Small framed advertisements posted at eye level above men’s urinals have been around for years, as have, for that matter, advertisements printed on the plastic screens inside of urinals.

The new video-ad mirrors will be mounted in both men’s and women’s restrooms.
