Home Box Office and Verizon today announced an agreement that allows Verizon to distribute HBO NOW — a service targeting Internet-only customers, across all of Verizon’s wired broadband networks, with the right to extend the service to Verizon Mobile customers in the near future.

Beginning today, HBO NOW is immediately available to all Verizon FiOS and High Speed Internet customers, starting with a 30-day free trial.

After signing up, Verizon customers can access the service by downloading the HBO NOW app on their Android phone or tablet, Amazon Fire Tablet, iPhone, iPad or Apple TV and selecting “Verizon” from the drop down menu of providers. Upon initial registration, customers sign in to watch their favorite HBO programming on their mobile device or on their computer at HBONOW.com. HBO NOW is currently available through Verizon to non-FiOS TV customers for a monthly subscription of $14.99 following the introductory free offer. FiOS TV customers can continue to purchase HBO, which includes access to the award-winning HBO GO app and access to HBO content on an anywhere, anytime basis on FIOS Mobile, through existing sales channels, including by using their FiOS TV remote control.

The agreement will allow Verizon to sell HBO NOW on its forthcoming mobile video platform, potentially under the umbrella of its Go90 service, expected to enter beta testing soon. No word on if Verizon’s mobile video platform will chew through your data usage allowance.
