This is one sick and horrible advertising idea, and I would never fault the editors for not publishing this one: but here it is....
When I first heard about the infamous pornographic â€œ2 Girls 1 Cupâ€ home video on YouTube, I was also told that if I did a search, I would be bound to find countless other videos of viewer reactions.
So here comes the advertising idea: since it is well-known that such reaction videos generate a huge amount of web traffic, periodic frames of billboard advertising between video clips could be very effective in improving one's product or brand recognition.
I know one might prefer to steer clear of associating their products with such videos, but it can be done in subtle ways (i.e. see the chocolate ice cream picture here).
