After a more than two year sales block on Apple's set-top media streamers because of "customer confusion," Amazon now has two "Sold by Amazon" listings for the Apple TV 4K.
The listings popped up overnight, and are not third-party sales. Both of the entries are for full retail price -- and are currently listed as temporarily out of stock, and no estimated delivery window.
Amazon withdrew the Apple TV and Chromecast on Oct. 29, 2015, after it claimed that Amazon Prime Video compatibility was necessary for the company to sell set-top boxes to avoid "customer confusion." Amazon could have made that happen with a channel in the third-generation device, or an app for the fourth-generation, but at the time it chose not to do so.
In 2016, Amazon CEO Jeff Bezos suggested Prime Video would remain off devices made by Apple or any other company marketing comparable set-top streaming products until amicable reimbursement models are agreed upon.
Apple CEO Tim Cook announced at the WWDC that Amazon's video streaming service would be available on the Apple TV in 2017. After several false starts, the app hit the Apple TV third and fourth generation, plus the Apple TV 4K on Dec. 6.
