Will Roku be adding the Lindell TV App to the available Apps at the Roku Store?
It's not up to Roku to add channels. It's up to the providers to create the channel for the Roku platform.
Let's hope not. There's already too many ways to spread the craziness.
You can watch LindellTV and LindellTV2 on Frankspeech for Roku.
