Teasers will suck you into watching more TV than you want to.

A teaser is a small preview of an upcoming segment or show that gives you enough of a glimpse of the clip or program to get you interested without giving away the ending or meat of the clip.

A teaser is designed solely to keep you watching television. For instance news shows (or entertainment news shows even) will say things like "Coming up next, 3 simple secrets for eternal youth".

Now of course, there is no such thing as eternal youth, but when you hear this, your brain says to your body, "Don't get up, there might something to this. Farfetched I realize, but you can afford to watch five more minutes of this crap in exchange for a shot at eternal youth."

Five minutes go by and all you've learned is that the early bird gets the worm, an apple a day keeps the doctor away and flossing your teeth will keep your smile white and bright. None of this gets you eternal youth, you've wasted five minutes of your life and the teaser has done its job.

There is an easy solution to this. Watch TV with your laptop or computer nearby. When you hear things like "Coming up next, Toby McGuire's big secret" grab your computer, fire up Google and do a news search for "Toby McGuire's big secret". Nowadays none of these programs will have a scoop on anything, so chances are extremely good that you'll be able to figure out what Toby McGuire's big secret is without having to watch another five, ten, fifteen minutes of TV to find out that he just had a baby.
