Did you read the article? They're talking about how AMC releases their content on iTunes, Amazon, and Netflix sooner than other networks. It's hardly exactly what HBO does.
While we're doling out "Did you read the article" comments, the article also mentions that HBO is in a league of their own when it comes to distribution. They have their own streaming network (HBO GO) and new espidoes are released immediately.
I think HBO definitely had a strong hand in pioneering AMC's current model.
HBO seems to have a very different approach to online distribution though - HBO GO only works if you already have an HBO subscription through a traditional television provider, and if the last season of Game of Thrones is any indication they don't put their shows on iTunes and Amazon until long after they air.
It's a riskier approach, because in order for it to work they have to get their app in all the same channels and devices that Netflix, Hulu, et al have already gotten into. And they have to train viewers to look there for HBO content instead of in their usual outlets. All of which is challenging.
But it's also potentially more lucrative as well, since if it works HBO won't have a middleman sitting between themselves and their viewers the way they currently do with cable companies and streaming services. And if HBO GO has enough compelling original content to get people to use it, they can then use that as leverage with movie studios for better deals on movies to distribute that way as well.
They also seem to keep the new seasons a secret. I missed the new Breaking Bad and missed most of The Killing this season (too late to even catch up online).
I'm at the point now where I'll just wait a couple years to catch it on Netflix.
AMC makes their shows available for streaming on Netflix faster than any other network that I'm aware of. All past seasons of Breaking Bad are available already. They usually make each season available for streaming soon after the DVD release, and before the next season airs on TV.
