YouTube TV arrived in April of this year, making it Google's de facto live television service. It's available in over half of the homes in the US, and we've been waiting patiently for the rumored big screen TV app so we could stop sending live TV from our phones to our Chromecasts and Apple TVs. The Xbox and Android TV versions of the app have been out for a few weeks, now, while Google tweeted out the availability of the YouTube TV app specifically for owners of newer model Samsung sets.
