They are displayed in two cases:

1) When you turn your Kindle off, there will be a full-screen ad.

2) When browsing books at the main menu, a small horizontal bar across the bottom of the screen will display an ad. You only come to this screen by choice, though -- if you were in the middle of a book when turning off your Kindle, when you turn it back on it will go straight to where you were in the book without showing this menu.

Since they never interfere with reading, they are extremely non-intrusive. I think they are personalized but not positive.

Considering that Amazon knows about most of my online purchases from the past 10 years, the kinds of ads they show indicate that they are not at all targeted. Almost disappointingly so.
