Public Toilets as Billboards

If you can't get enough advertising wherever you go (do we really need full-color ads on grocery store floors?), another method has been invented to continue this endless bombardment with the "Wow Toilet". It consists of an inner tank with an exterior clear component into which advertisements are inserted. I wonder who thought it might be a brilliant idea to associate a consumable product other than toilet paper with going to the bathroom, but apparently this is starting to catch on.

To me this raises a few questions:

How intrusive has advertising become?
Should a public toilet double as a billboard?
Can't a toilet just be a toilet?

I fear that this might catch on as a "clever" way to decorate in the residential world. I can see it now...little girl bathrooms with an inserted unicorn. Fratboy toilets with centerfolds. American flags hugging the tank (if you've seen flags masquerading as bandannas on sweaty heads, trust me, you'll see them as a patriotic statement on a toilet tank). You get the picture.

The good news is that the water tank has a dual flush option...score one for the planet.
