For watching tv when it has too many commercials and not enough interesting content, You Tube tv lets you watch two tv's or two lap tops at the same time.
So's, you get to view both Sean Hannity and Rachel Maddow at the same time, live, side by side .......
Ditto that for watching two tennis matches simultaneously ...... ha-ha-ha .....
..
Plus, maybe 30-40% of all commercials get blocked out and replaced with a You Tube tv screen filler short probably because the advertiser is a no-pay ..... and no-pay makes it a no-play.
