This means that the Amazon Fire TV product range now has all of the UK catch-up services available on it.
These free on-demand digital catch-up services from ITV and Channel 4 join existing offerings from the BBC and Channel 5.
"With BBC iPlayer, ITV Hub, All 4 and My5, every single UK customer with a Fire TV or Fire TV Stick now has access to all of the UK’s most popular catch-up services," said vice president of Amazon Devices EU, Jorrit Van der Meulen.
These join non-terrestrial video services such as Amazon Video, Prime Video, Netflix, UKTV Play, YouTube.com, Vevo, and Curzon Home Cinema, among others. Amazon says that it now has 4,200 channels, apps and games available for its Fire TV devices.
