I opted for the ad-free Hulu subscription, and that, for the most part, is great.

They do have a few programs on there that are not eligible, but then they say up front "due to streaming rights, we have to show you ads, but it's just one before and one after".

That, at least is better than the ad-laden Hulu before they offered that option, where any prolonged bout of streaming would show you the same ad over and over and over.
