If you’re already sick of seeing an endless stream of videos posted on your Facebook feed, buckle up, because its not going to slowdown anytime soon.

Companies are increasingly turning to online video to market their products, with a shade more than $4 billion spent on US mobile video ads in 2016, according to the latest Global Entertainment and Media Global Outlook report from PriceWaterhouseCoopers. More remarkably, this figure is expected to nearly quadruple to $16.2 billion spent on digital video by 2021.

As the report put it, online video advertising “will continue to grow as the quality and quantity of video ads served increases, while the planned rollout of 5G networks will further accelerate the shift towards mobile consumption of video.”

The influx of ad dollars only incentivizes publishers, networks, and creators to double down on their video output. Earlier this week, Fox Sports laid off 20 writers and editors and said it would focus its efforts on digital video. Buzzfeed and the New York Times, among other publishers, have a small army dedicated to churning out video. “The impetus for publishers and broadcasters to generate more inventory to fulfill demand – especially on mobile devices – is clear,” noted the PWC report.

At the same time, social platforms are gearing up for the coming flood of online video.

Facebook is set to launch its slate of advertiser-friendly shows later this summer, and Snap just inked a deal with Time Warner to create original content and run ads. Instagram has become the platform-of-choice for niche creators looking to attract Gen Z eyeballs. And, oh yeah, YouTube just announced it hauls in a mere 1.5 billion viewers each month.

These outlets, as well as advertisers, see the writing on the wall: online video is about to take off, and with it, the money grab for ad dollars.

'Minority Report' and 18 More Movies That Accurately Predicted Future Tech (Photos)

Steven Spielberg's tech-heavy "Minority Report," starring Tom Cruise, is now 15 years old.

20th Century Fox
Long before Siri, there was HAL. The ominous yet soft-spoken computer system was the antagonist in 1968's "2001: A Space Odyssey." Stanley Kubrick's sinister talking computer ended up turning on its crew in a Siri user's worst nightmare.
MGM
Tech giant Elon Musk is at the helm of SpaceX, which will send two tourists to space in 2018. But "2001: A Space Odyssey" imagined commercial space travel decades ago.
MGM

TriStar Pictures
"The Terminator" predicted military drones in 1984 -- long before they were introduced to police forces and militaries.
Orion Pictures
Virtual reality is taking over the tech scene. You can play games in VR, watch movies and experience Coachella all from the comfort of your living room. But Hollywood predicted we'd have VR more than 20 years ago in 1992's "Lawnmower Man."

Remember when the TSA rolled out invasive body scanners and a lot of people freaked out? "Airplane II: The Sequel" imagined airport scanners that revealed a person's naked body to agents.
Paramount Pictures
Just like other industries, robots are taking over jobs in the military, too. There are even listicles outlining the "coolest" military robots. "Short Circuit" predicted this technology with the prototype robot Number 5.
Tristar pictures
Woody Allen's "Sleeper" had robots assisting surgeons by offering advice during surgery. Today, doctors use robotics to add precision to procedures.
United Artists
The beloved 1960s cartoon "The Jetsons" -- which was made into a movie in 1990 -- predicted the use of robots to clean homes. They had a robotic vacuum and a robotic maid. Can you say Roomba?
ABC
In vitro fertilization and at-home genetic testing are common place these days. "Gattaca," with Uma Thurman and Ethan Hawke, predicted this tech in 1997.
Columbia Pictures
3D printing is used today in industries ranging from aerospace to medical. In "Weird Science," the boys 3D printed an actual girl.

MGM
FaceTime, and Skype before it, are commonplace today. But it was cool new technology in 1989's "Back to the Future Part II."
Universal Pictures
There are a ton of different options out there for smart watches. This was predicted in 1990's "Dick Tracy."

Columbia Pictures
Tinder, Bumble and OKCupid are only a few of the many, many online dating options out there. But Meg Ryan and Tom Hanks were on the forefront of the online dating trend in "You've Got Mail."
Warner Bros.
VR porn is growing in popularity. Or as it's called in 1993's "Demolition Man" -- "digitized transference of sexual energies."
Warner Bros.
The 1929 movie "Woman in the Moon" predicted space travel. Obviously, we hit that milestone decades ago. And hey, they even got the shuttle shape right!
