Netflix has a big problem.

As it gradually shifts its operations towards more instant, on-demand video streaming of movies and TV shows subscribers want, some well-connected studios and distributors have a vested interest in stopping Netflix in its tracks.

Among the most threatened is Time Warner’s HBO, which has watched premium movie channel subscriptions erode for years as consumers dump pay-TV for lower cable bills and Netflix subscriptions.  For up to five dollars less than what cable systems charge for HBO, Netflix customers get access to unlimited video streaming and can still check out one movie at a time on traditional DVDs.

Netflix is slowly evolving their business towards streaming and away from costly and labor-intensive DVD rentals-by-mail.  Customers enjoy the instant access to programming — no waiting for the mail or getting on a waiting list for popular titles.  Netflix does not have to pay ever-increasing postage rates either, or replace lost or damaged DVDs.

But for Netflix streaming to succeed, the company needs agreements with content producers — Hollywood studios and distributors — for so-called “streaming rights.”

One contract wins the right to obtain and rent out the physical DVD’s, which Netflix has had no problem in obtaining… eventually.  But another, separate agreement is needed win the rights to stream movies or TV show over the Internet.

So far, most of Netflix’s streaming agreements cover older movies and TV shows that have already found their way to Hulu or have been run to death on premium movie channels.  Anyone for Big, Fast Times at Ridgemont High, or Class Action?  These are all listed by Netflix as “new releases.”

Now Netflix wants to expand their library to include additional titles and they’ve run into a roadblock – HBO.

The premium movie channel controls streaming rights not just for its own programming, but also for Warner Bros., 20th Century Fox, and Universal.  Those three movie studios produce an enormous amount of movies and television shows, and without being able to contract streaming licenses, Netflix may be in big trouble.

HBO's Go service streams HBO movies, specials, and series to "authenticated" HBO subscribers

HBO intends to keep those shows, as well as its own, exclusively for itself and its cable and telco-TV partners.  As part of the TV Everywhere concept, HBO will dramatically expand its own streaming movie service — HBO Go, currently only available to authenticated Comcast and Verizon FiOS HBO subscribers.  Everyone else can forget about it.

The pay television industry — cable, satellite, and telco-TV, is more than happy to accommodate HBO sticking it to Netflix.  HBO Go could help sustain the premium movie channel and sell more subscriptions.

The video war means that Netflix will be in the DVD rental-by-mail service for years to come, if only to serve up movies and TV shows from those three studios.  More likely, however, is that Netflix will find a partner to help return fire — denying HBO access to movies controlled by Netflix.

Ultimately, consumers are likely to follow the content.  If Netflix controls it, consumers will sign up for that service.  If the cable industry controls it, they’ll be forced to keep their cable subscriptions.  It’s a high stakes game either way.
