HBO is the best value on my cable bill, right after the 100mbit internet.
Really!? you might ask. $15/month for that? Well, yes. I like the programming (this is the network that brought us "The Sopranos", "The Wire", "Game of Thrones", "True Detective", and I could go on and on ("Last Week Tonight", anyone?). All this with no commercials, because I paid for superior programming without commercials.
I get the HBO GO service for that same money, and I can time shift what I want to watch with a ChromeCast, and I can watch just about all of HBO's original programming with the HBO GO service -- not just the current stuff. Sure, I'd like it better if it was $10/month.
With HBO NOW, HBO has figured out how to cut the need to actually buy cable TV out of the picture. You can just subscribe and buy their content over the internet directly.
What I'm waiting for is true a-la-carte television, with real options. Pay $15 a month for HBO, or $3/episode for "Game of Thrones", or don't pay, but answer surveys or watch advertising to watch for free. People who don't want ads could pay, people who have the time but not the money could fill out survey or watch ads to watch for free.
