@imrainmaker Having two or more subscriptions to content for cable or internet. I have cable and internet. Will get specialty channels exclusively to different providers on the 26th of Oct 2018. For $25. Mainly radio stations on cable that I would not normally get.
Where I live, most people get both cable TV and internet access through the same single connection. It is possible to get content through either connection; I can get HBO via the HBO channels, or access HBO Plus via the internet.
