What's that carbonated beverage sold in vending machines?

They've always been to referred to as "Soda" to me.

I know someone said it's soda in the midwest, but I'm in the midwest, and it's always been pop. Well, it can be heard by all terms, but, is always most often called pop. Minnesota FTW B|

i live in southern california and we say soda but my cuzins up northn sau pop so its cultural mostly like annotation of potato or tomato or caramel

I've always called it cola

Midwest here, usually I'll say pop in ordinary conversations and it's common for people here to refer to it as pop but if you look at signs, menus, etc. they will usually say soda and both are interchangeable if you're talking about them. Rarely you will hear soda-pop and if you ask for a coke here you will get a Coca Cola.

That said I usually use soda online or in unfamiliar company.

We have many names to use to specify a fizzy drink here, But we rarely use them on a normal conversation. (Unless needed.)

What we usually use is the name of the drink and apply a little Arabian accent.
(Example: Pepsi = Bebsy, Cola = Kolah.)

Soda, older people around here call it pop but that's about it.

I'm gonna go with soft-drink because vending machines can have sodas, juices, teas, sometimes even cold coffee in a can.

Well in my area, people mostly call it coke.

Here in the Netherlands -- at least where I come from -- we mostly call it 'een blikje' (literally: 'a can') which can mean any form of soft drink. If we specify what we are buying from the vending machine, we use the the brand, but in a diminutive form. 'Cola' (Coke) becomes 'colaatje'* and 'Fanta' becomes 'fantaatje'* for example. It's both a display of fondness for the beverage in question as it is a somewhat lazy, casual way of saying it.

*Note that the literal translation for 'colaatje' and 'fantaatje' are 'little coke' and 'little fanta', but it's actually more comparable to the use of 'daddy' instead of 'dad' in English.

In my area it is 'cola' but most people call it 'Coca Cola'.

"Coke" is a brand name, so soda. I drink more Coke than anything, though.

I call them by their brand names.

In England we call it Pop :3
Well at least i do xD

Soda wins. If you call it "pop" then freaking stop it.

I live in central Illinois. Around Peoria.

It's "pop," silly gooses.

NORTHEAST OHIO REPRESENT

purple drank, Orange drank, coke, cream soda.

U CALL IT BY ITS FLAVOR~

Here in Chicago and in most of the Midwest, we call it pop.

In a couple of places i've lived we didn't even really have soda machines really only fizzy water and/or fruit/vetgie drinks
