I believe they are getting (NBC) seeing that from youtube.
But sports and movies are hour long.
Most viewers viewed in youtubes are 2-5 min clip video.
Thats where smart tv's come along now. Hooking up your smart phones to the big screen for those viewing that you really need to have
A beer on your hand
Or a popcorn
IMO
Highlights, clips and stats are good in small screen.
But movies and live sports are needed to be watch on bigger set with surround sounds
But yeah
We use our smart phones more.
Heck we spend more time with the smart phone than with our families. Most anyways
