Digital Trends – Earlier this week, Roku rolled out an update that offered access to the HBO GO application. Assuming that a Roku owner is currently subscribed to an approved provider, users can download the application and watch the latest in HBO original programming. However, HBO doesnât provide any method to subscribe directly to the service due to existing relationships with cable and satellite companies. A Roku owner must be subscribed to HBO through Verizon FiOS, Cox, Charter, ATT U-verse, Dish Network, Massillon Cable/Clear Picture, WOW!, Suddenlink or RCN to gain access to the programming. This method of access goes against how some of the public views the streaming device as a way to ditch expensive cable or satellite service.
