How do I add HULU to my Apple TV?

Do you have the Apple TV box (4th generation or later)? Identify your Apple TV model - Apple Support

Only then you can add the Hulu app through the on-device App Store: Find apps in the Apple TV App Store - Apple Support

The Apple TV App Store is not available on Apple TV (3rd generation or earlier). What is offered is what is available.

The Apple TV App Store is not available on third party devices with the Apple TV app. See what apps are available from the app repository as offered by the device manufacturer.

That is helpful, thank you.

A1469 is a 3rd generation model, which unfortunately isn’t compatible with the services from Hulu. Hulu has decided to not support this model.

That is great! I’m glad to hear that AirPlay still works for this.
