You’re not alone.

The first thing to know, Snapchat isn’t just about sending selfies anymore.

Now they’re pitching themselves to investors as a camera company,

and unlike Facebook and Twitter,

Snap isn’t just about ads and a native feed.

In fact, core to their concept is creating content

And that's what its five revenue generators are all about:

Lenses, Geofilters, Snap stories, Discover and Spectacles.

First up, Lenses

Open up the app, and BOOM!

You’re straight into the camera

Brands can then pay up for filters

that you can overlay onto your photos or videos

and then send them to a friend or to a group.

Geofilters do something similar,

overlaying the “where” and “when” that businesses or people can pay to include in an app.

Now I can also send my Snaps to my Snap Story,

a feed that friends can see before a Snap disappears after 24 hours,

which brings us to our third revenue generator:

“Our Story.” It’s basically a group feed that Snap goes through

and grabs publically posted Snaps and puts it into one video feed.

You’ve seen this around events like the Women’s March or Trump's inauguration.

And everyday people aren’t the only ones uploading to Snapchat.

Enter “Discover.”

Starting in 2015,

brands including People, BuzzFeed, ESPN started uploading mobile magazines that

create stories in more millennial-friendly versions

with ads slotted in between, of course.

And you can’t forget the “Spectacles.”

You can grab these suckers for 130 bucks

at the pop-up vending machines that Snap has put around major cities.

You take ten second videos with them

like I did on the mountain last weekend,

and then it goes straight to your Snapchat app

as soon as you connect to wifi.

And let’s just mention for a second

that advertisers for a while have been pretty weary about using Snapchat

because they are so insistent on vertical video ads

when advertisers are much more used to the horizontal shape of TV,

but they’re warming up to it.

Has it worked?

Well, the true test will come in the years after Snap goes public

because their revenue model is still only a couple of years old.
