Both shows will be streaming exclusively on Showtime's own service - Showtime Anytime.
Netflix is an obvious threat to premium cable channels. That's something HBO has known since day one, but others like Showtime have been a lot friendlier with the streaming service. That seems to be changing.
While the new deal between the two companies will include streaming rights to shows like 'The Tudors' and 'Sleeper Cell,' two of Showtime's biggest shows are being pulled. Both 'Dexter' and 'Californication' are being removed from the service.
The deal ends this summer, so if you're watching either show on Netflix, you've got plenty of time to finish. If you haven't started yet, it's time to get on it.
