This is a rather new way to market a product or a company. The idea is very simple:
You begin to distribute small programs that are usually quite humorous.
Here are a few:

Bill Clinton as the Cat in the Hat
La Cucaracha
The Frog in the Blender   (Okay sure this is an example of bad taste)

(To copy them on to your hard disk you may have to use the right button if you have an older PC.)

At the beginning or end of the show you place your name & address or that of the company that
you wish to promote. Soon million of e-mails are flitting about with your ad attached. Creatively expensive but cheap as far as ordinary advertising costs go .
