I see that this season, Kabaneri of the Iron Fortress is being streamed by Amazon, which holds exclusive distribution rights to the series and will also hold exclusive distribution rights to other series on the same network as Kabaneri in the future.
Even though I know that Amazon had acquired exclusive distribution rights to other non-anime series like Under the Dome, I was a bit surprised to see an anime title be subjected to exclusive distribution.
That led me to wonder: have there been any other anime that have been subjected to exclusive distribution rights in the past? In particular, by a party not dedicated to anime distribution like Amazon?
