Junk food like McDonald's and Snickers bars have been shown to be addictive.
They are all the same type of product. It's amazing to see those involved in tech attempt over and over again to rationalize themselves out of that obvious connection.
The though occurred to me, that those highway signs with the mini ads for the gas stations and restaurants coming up could include products you'd be able to get at said gas stations and restaurants... Snickers could be on the sign, right next to Chevron or ARCO. That would be relatively cheap for some larger brands (Coca-Cola comes to mind), but potentially huge in terms of placement.
Gah, I hate that I come up with ways in the back of my mind on ideas like this... still it's better than the over-the-top ads in the clickbait sites.
