The whole problem with sling Tv is that it's a toy.
Oh that's neat, I can get a handful of channels on my Roku. Let's do a 7 day trial, and maybe forget to cancel after the first month.
The problem is that it's not replacing the way people watch tv, people are not going to dump their cable subscription to get sling.
The people who are truely cutting the cord bairly want to pay $30/mo for a decent internet connection.
I disagree with this part. I'm 28 and more of my friends are cord cutters than cable/satellite customers. I'm actually one of the exceptions but only because I got a really good deal that bundled Charter's equivalent of AT 250 plus HBO, Showtime, and Cinemax for $30 more than I was paying for 60Mbps internet on its own. I already had a Tivo Roamio so I don't have equipment fees. Before that offer came along I was a cord cutter for almost 2 years though.
One thing that all of my cord cutter friends have in common is a good internet connection. We didn't cut the cord because we are cheap or can't afford cable. We are all actually doing pretty well as college graduates in professional fields. We cut the cord because cable/satellite isn't important to us and we don't see the value of paying $100+ per month for it.
We do stream video and get our music, games, books, etc from the internet though. Because we get all our media through the internet, that internet connection is way more valuable to us than a cable subscription.
Here is a reason I think people my age have this kind of attitude towards TV. Tivo came out in 1999 and every cable/satellite provider started implementing their own DVR options. For people like myself who are 28, DVRs have been around for over half our lives. Since we were 12-13 years old we could watch the content we wanted to watch, when we wanted to watch it. We have spent more of our lives being able to watch TV on demand like this than we did before when we had to tune into channels and watch whatever they were putting on. The generation younger than me will have even less connection to traditional TV channels than mine does.
Netflix and other streaming services are just a natural evolution of that in my opinion. At some point you just care about the content. If its convenient, high quality, and cheap it doesn't really matter what the delivery method is and it certainly doesn't matter what traditional TV channel it came from.
That being said, my friends don't care about Sling TV for the same reasons they don't care about cable. They didn't cancel cable because they cant afford it. They did it because they don't want to buy the product being sold. Selling that same product through an internet subscription doesn't change the product. Services like Netflix, Amazon Prime, and Hulu Plus are much more popular than Sling TV for a reason.
