How often does it show advertisements?

How many Wii U games are there anyway?

Would you expect the Wii U to do some sort of correlation (other people that own the same games A & B also own C, so you're probably interested in C)?

I cannot remember that it have ever showed one while I was sitting and reading an entire evening. But as soon as we start talking it will show advertising. That could be explained that it simply detects noise in the room, but it correlating to what we're talking about more often than not.

There's an option to disable it waking up and displaying things, so I've never seen adverts on mine (but maybe there's other things shown you do want to see?)
