Interesting and smart advertisement.
Imagine you’re reading a magazine and you see an ad with what you suppose to be a very cute girl in sexy lingerie or something like that. But the parts you would like to see are missing, just erased by some white rectangles. As you’re curious by nature, you have to send a SMS after 9 pm to receive the missing parts.
