“The Blaze” works fine in the Roku. Requires a subscription of about $10 a month. You can get some Fox News but it is limited. An HBO service called HBO-GO is available if you are an HBO subscriber, but it is also limited in content. There are many, many other services - news, radio, old movies - available. Hulu Plus and Amazon Prime - both about $10 a month each - are available. I have not tried either but you can test them out for 30 days for free.
All in all, Roku + Netflix is a winner.
