Is "a premium brand" a main obstacle preventing new entrants into the content production market? There is another large obstacle: acquiring subscribers to fund the production. Netflix already has a massive subscriber base. HBO needs to convince people to subscribe to their content and to watch their content. Netflix already convinced a massive subscriber base to subscribe to its content. Now all it needs to do is convince them to watch it.
EDIT: I think my post addresses filmgirlcw's point well. Yes, it took 15 years for HBO to cultivate their seal of approval. But that is partially because cultivating a seal of approval required HBO to build its subscription base, which takes time. Netflix already has its subscription base, so it only needs to convince that subscription base to watch its content. It can do that by 1) advertising prominently within Netflix (near zero cost), and 2) producing quality content, so that once people watch the first episode of a Netflix show, they want to watch the second. Therefore, the highest cost to Netflix is that of producing quality content. But as long as they can do that, they will succeed because they already have the audience. Of course, they do need to recognize that they only have a small window of opportunity to show that they can, in fact, produce quality content -- or else they will lose the willingness of their subscriber base to watch their originals.
But Netflix has to retain that audience. As we saw with the price hike, people by the millions will drop their subs and fast. TV is a hits based business -- HBO has to deal with that too, post Sopranos and SATC, it struggled for a few years to find the hits.
I'm also not sure if you understand that HBO has has subscribers in the tens of millions for decades. That's my point, they've cultivated this premium brand but have been a part of many customers lives for years. I'm 30 and I've never NOT had HBO.
My parents have had HBO literally since 1972. 41 years. I realize that's an extreme example but the network has a strong brand.
HBO and Netflix aren't in a zero sum game; both can succeed. It's just that as Netflix moves into HBO's pool, it's going to have to face the issues HBO already faxed, whereas HBO won't have as hard of a time shifting to over the top once the business model makes sense.
