Amazon has decided that however many trillions just isn't enough money for them, so they've decided to sell ads in their Prime video. Oh, and if you want to opt out of ads it will cost you an additional $2.99/mo.
We are writing to you today about an upcoming change to your Prime Video experience. Starting January 29, Prime Video movies and TV shows will include limited advertisements. This will allow us to continue investing in compelling content and keep increasing that investment over a long period of time. We aim to have meaningfully fewer ads than linear TV and other streaming TV providers. No action is required from you, and there is no change to the current price of your Prime membership. We will also offer a new ad-free option for an additional $2.99 per month* that you can sign up for here.
