Max, the forthcoming streaming service from AT&T Inc-owned WarnerMedia, announced on Wednesday several new partners will carry its content, but it has not yet announced deals with Comcast Corp, Amazon.com Inc or Roku Inc.
Cox Communications has announced a similar deal, to give Cox Contour's existing HBO subscribers access to the new service, as has Altice.
However, it does not appear that there's any chance HBO Max will be available to Amazon Fire customers at launch.
WarnerMedia and Roku are now in negotiations on a pact for HBO Max, a Roku spokesperson confirmed to Variety.
Max will be available on Altice USA Inc, Cox Communications, Microsoft Corp, National Cable Television Cooperative (NCTC), Samsung, Sony Interactive Entertainment and Verizon Communications Inc when it launches on May 27, the company said.
So for the subscriber, it's nice that they can access the HBO Max App, even if they sign-up through a third-party - but it's a bit of nuisance that they can't get all their content from their cable or streaming provider's native interface.
HBO Now debuted in 2015 as a stand-alone streaming service with HBO series, specials and movies. Customers will be able to log into the HBO Max app on supported devices or access it on desktop and log in using their Cox account credentials.
A WarnerMedia spokesperson told Variety there was "nothing new to report" vis-a-vis a deal for HBO Max on Roku.
HBO Max will be made available at launch to independent cable and broadband operators - including WOW!, Atlantic Broadband, RCN, Grande Communications & Wave, and MCTV - through a new agreement with NCTC.
The headline is that Warner has reached an agreement with Verizon to make HBO Max available at no extra cost to current HBO and HBO Max subscribers to Fios TV and Internet.
HBO Max will be available on the PlayStation 4 and Xbox One gaming console systems at launch.
