The HBO NOW subscription will cost $14.99 per month, with no long-term commitment required. Customers will get a free month upon signup from Apple TV, iPhone or, iPad devices. The service will launch in April, 2015.
A separate service, HBO GO, is already available on Apple TV. But unlike HBO NOW the service requires a subscription to the network through a cable or satellite provider.
Dish recently released the Sling TV OTT service that offers a suite of channels for $20 per month with no contract required.
