If so, you weren't watching Netflix.

You see, Netflix doesn't rely on ads to support, grow, and source its revenue.

Unlike Hulu and Amazon Prime Video, the world's leading streaming service offers every single customer a completely ad-free viewing experience.

So without ads, how does Netflix manage to make money?

In this video, we're gonna break down exactly how Netflix's unique business model allows it to capture such a sizable audience, and how its vision for the future could cement the streaming disruptor as a bona fide media titan.

In 2018, Netflix brought in a total of 16 billion dollars in annual revenue, up 35% year over year.

The online streaming platform also grew its net income to 1.2 billion dollars last year, double what it was in 2017. But where does that money come from? 

All told, roughly 139 million users pay between $8 and $16 to Netflix to stream shows, documentaries, and films every single month.

In fact, in the U.S., Netflix's biggest market, estimated 54% of households now have the streaming service.

That's a lot of people binge-watching in their pajamas.

Last year alone, Netflix accounted for 10% of all overall screen time in the United States, which adds up to 100 million hours of television per day. 

More eyeballs means more stream time, and for Netflix, more paying members.

But it's not just uninterrupted reruns of The Office and Friends that keep Netflix at the front of the pack.

Netflix, which started as a DVD rental company, also produces its own original content, shows you can't find anywhere else and just can't put down.

The company's created full-blown frenzies with its original content, so much so that releases like Bird Box have become cultural events.

The company estimates around 80 million member households watch the blockbuster in the first four weeks following its release.

Netflix has been a steady hit-maker with its originals, and created tentpole franchises with House of Cards, Stranger Things, and Ozark, among others.

These titles build buzz, bring in new members, and keep loyal fans happy, but they don't come cheap.

Instead of licensing this content, Netflix is paying the upfront cost to produce and market it.

In 2018, the company spent around 12 billion dollars on content, up from 9 billion dollars the year before.

And in 2019, the company is targeting a content spend of 15 billion dollars.

While Netflix is profitable, on a cash flow basis, this content spend actually takes the company negative.

In 2018, Netflix had a free cash flow of negative 3 billion dollars, and they plan to burn through an additional 4 billion dollars next year.

You heard that right -- that's billion, with a B.

The company is taking on debt to build out its content library of originals.

The plan is to eventually scale that spend down over time as the archive becomes so big that even the most avid binge-watchers can't cruise through it all.

It's a bold strategy, but so far, it's working.

As of today, Netflix is the seventh-largest internet company in terms of revenue.
