I like this point. But actually that has already happened to an extent offline even if it hasn't much online. Billboards are often sexual or colorful -- even beautiful: they are created by graphic designers. Adverts often have music that we enjoy. Some restaurants try to advertise their food by wofting the smell towards us, etc... However it could go a lot further. I'm surprised people aren't spraying women's perfume/pheremones on adverts for Lynx for example...
