Sometimes I really do wonder about these web ads.
I was on Yahoo Finance (of all places) and saw an advertisement for some kind of skin cream. I've put a composite image together showing several "stages" of the ad.
The area marked 1, on the left, is the original ad, which appears to show a horribly disfigured burn victim. Part 2, in the upper right, is when I move the cursor over the ad, which allows me – – for reasons that aren't readily apparent – – to draw on this poor soul's face with impunity.
Finally, section 3 shows the result: a complete hottie (although perhaps a different moniker would be more kind, given her earlier unfortunate post-burn circumstance).
As if you needed to be told, this ad reminds the reader that the images are "simulated." Thank God.
