So far it's been mostly ads for other netflix shows, but they are everywhere. Full screen ads you have to click through to even get to the catalogue, a giant ad at the top you have to scroll past, ads taking up multiple rows as you scroll through their options, the ads that play in the middle of a show if you pause the screen for more than a few seconds, the ads that play as soon as the credits start rolling (even when there's still content), etc.
