As far as I can tell there isn't one. Even when you pay extra for no ads the interface itself is infested with them. A truly ad free amazon prime tier wouldn't constantly push shows and movies you that you have to pay for on top of the higher monthly fee you're already paying for or show ads for shows and movies on other platforms.

They're clever with that, by offering subscriptions to various producers and other streaming platforms within Amazon Prime video UI. The Amazon subscription is very cheap, but then you end up sub-subscribing to SkyShowtime and MGM and Apple Video to get access to your favorite space shows, and suddenly it's cable 2.0.

Wouldn't be so bad if the player didn't suck. You'd think video streaming chrome would be a solved problem by now, but it's not, and somehow we're regressing on this front.

Hulu "no ads" is even worse.

Live TV? Ads. Shows available as part of streaming packages for channels included in live TV? Ads. Random other stuff "due to streaming rights"? Ads.

At this point I pretty much assume any non-Disney programming that isn't a Hulu original will have ads, and access it by other means, partly as a minor act of civil disobedience, but mostly because I'm impatient (i.e., never in my life have I actually watched television advertising, even when forced to sit through it).

It is called: Prime Video Ad Free

Go to the Prime Video website, or check your settings in Prime Video on your device.

I have lived a video ad free life for decades. I am convinced video ads do bad things to our brains. In aggregate, beyond any individual impact they may or may not have.

Ad blockers, ad free YouTube, Kagi, … whatever it takes.

Two to five years ago. :P depending on how you feel about their cross-promotions (which are ads, but at least aren't inserted into the content)

It's called Flixer.
