Disclaimer: Our household uses YouTube TV and we also use it in our offices. The reason for that is because it works well whether on mobile a smart TV or an iPad. Google has clearly provided a better experience and service (unlimited DVR, mutiview, etc.) when compared to the satellite and cable providers. The numbers clearly show that and it seems they believe they can broach 30mm subscriptions.
Legacy providers have been beat for now. This household has our subscription.
