Regarding your Sling Blue comment, do you know if the Discovery Channel offerings are part of their lineup? I looked and didn’t see it. Wife loves watching her Joe Kenda episodes.
If you use Amazon Fire TV you can get the free app for Discovery:
Amazon.com: Discovery GO: Appstore for Android
https://www.amazon.com/Discovery-Communications-GO/dp/B01M2WG1YZ
Product description. Watch full episodes and live TV from Discovery Channel anytime.
As the cord cutting continues to grow, watch the slimmed down providers and powerhouses like Amazon Fire TV add free apps or apps at low cost for the apps.
