What is up with all of the teeth whitening product ads?

They're all over the internet. I just don't get it. Did they run out of ideas?
--------------------
I was just at the Affiliate Convention in Denver and they confirmed that teeth whitening is the "hottest" thing in affiliate advertising right now and has been for some time - many companies have a product like this to offer and many publishers are running ads for them. It is a wide spread product that is gender, race, and age neutral. You might have noticed a ton of Acai berry ads for some time, but those are generally geared toward adult women, where as teeth whitening appeals to a much broader audience. As someone who is quite familiar with this product, I can also tell you that the offer is so popular because it is a natural continuity model (they send you a refill once a month to continue whitening) and the relative cost of the product compared what they charge is significant - in other words, you make a ton of money off of it as an advertiser. If you are a publisher, payouts for whitening offers are high on affiliate networks as well. So, in a nutshell, you are seeing a lot of whitening offers because people continue to buy it. :-) Advertisers continue to try new ideas and run with them, but so far nothing is working quite as well (facial products, weight loss, etc.). When the next big thing hits, you'll see a ton of offers for that and teeth whitening will slow down.
