BritBox is now available in around 15 million homes after being made available on Amazon Fire TV.
The subscription service is accessible via Apple TV, Google Chromecast, netgem.tv, Smart TVs, as well as desktop, and Apple and Android smartphones and tablets.
It is expected to launch on YouView and other Freeview Smart TVs “in the coming months.”
While the service is now available to 15 million homes, it has yet to reveal how many actual paying subscribers it has.
