The 90 day embargo marks a departure in the chummy relationship between Starz and Netflix.
Since early on, Starz and Netflix have been working hand in hand. They seem to get along well. Starz gives Netflix plenty of content and Netflix gives Starz its own category in the streaming section.
The once friendly partnership is making a change on April 1st as Starz will start embargoing its original programming and new release movies. That means you'll be about three months behind on 'Spartacus' if you're not watching it on Starz.
Steve Swasey of Netflix says that it's not going to happen. He says that Starz can't alter the way things work without renegotiating the contract.
