First I'll tell you where this trick originated from. In the 1900's a small network of movie theaters put in extremely short frames in between the frames of a movie that said things like: “Drink more Coke” and “Eat more popcorn.” The frames were to short to actually be acknowledged by our conscious mind, but the movie theater owners noticed that the sales did go up. Soon afterwards, they released their results to the public. The government shut this down, probably because this wasn't an honest way to make money.
How the Trick has been Altered
Next time you see a commercial, or a trailer for a movie at a movie theater, or anything else that may want your attention, watch for a small flash of light or something like that in it. Someone that may be casually sitting on the couch, not really watching TV, will see this flash and temporarily look at the screen again. This trick is not as frequently used on computer advertisements, because of the fact that most computer users, when playing games, are actively participating and paying attention.
However…
Next time you make a movie or advertisement, use this little trick. Start the movie with a slow flash of light or something. Something to get their attention. It grabs their attention and gives you a better chance of getting good views.
