Comcast (NASDAQ: CMCSA) is known as one of the stingier MSOs when it comes to extending multiscreen services for the streaming components of the premium programming networks.
So it comes as somewhat significant news that the cable operator is now letting its customers authenticate HBO Go and Showtime Anytime on Amazon (NASDAQ: AMZN) Fire TV and Fire TV Stick.
Comcast has already allowed authentication of the premium channels for Xfinity TV customers on Roku, AppleTV, Xbox one and Google (NASDAQ: GOOG) Chromecast.
Six years after the launch of TV Everywhere, however, the two streaming services are not available for Comcast TV customers to play on their PlayStation 3 and PlayStation 4 consoles. HBO Go's app has been available on PS3 since early 2004 and available on the PS4 since March.
Still, Comcast boasts that it allows authentication of more than 90 networks on 18 devices.
