I assume you mean the middle one in the attached image. It is simple its for babies because now they have them hooked on Pepsi like breast milk.

Did you make this face while you did it :p

Gonna guess that research showed that there is potential for sales growth at a lower price point, and that the way to meet that price point is with a smaller quantity of the same product. This has been a trend for a long time: as production costs go up, incrementally decrease the product size to stay within a marketplace-acceptable price range. The loaf of bread is a prime example; boxed cereal is another.

Whatever the reasoning, it's up to the consumer to decide whether it succeeds or fails.

If only I had a mustache and monocle...

But seriously, it wasn't that expensive either.

The fact that you neither have a mustache nor a monocle, tells us more about you than the fact that you don't drink "mainstream soda". Just fyi.

Well, I have a mustache, just nothing that exquizite. And I'm thinking of shaving mine off anyway. I should trim it first, however.

Won't make up for not having a monocle..

Would an eye patch suffice? We could send someone over to poke an eye out...

Excellent solution!

Darvond, please expect a visitor sooner or later ^^

Coca-Cola used 10-ounce cans only in Canada, where 10 Imp. oz. (284 ml, changed to 280 ml post-metrification) has long been a standard size. Master bottler Earl Dean's 6-1/2 ounce contour bottle is (was, the refillable bottles were last made in 2012) their longstanding symbol for nearly 100 years.

Reduce product size, and promote the hell out of it so consumers won't notice they're getting less for their money. Pepsico's not the only party guilty of this. Mass-market "premium" ice-cream makers have managed to get 64-ounce cartons down to 56 and now 48 ounces without any major protests.

I'll be sure to lock the door.

Coca Cola had 7.5-8 ounce cans in the US for a while, since 2006. I haven't checked for them recently but they do exist. Perhaps they didn't sell everywhere in the US, but they are available here.

People can limit themselves by being disciplined but I can see the usefulness of mini cans if you eat from lunchboxes and the appeal of how it looks, thanks to you. So thanks for shedding some light on this.
Why not just stop yourself from drinking a whole can? Save the rest for later?
If people want less sugar then they could just...drink something else instead of getting less for their money... There are plenty of other drinks being sold that have less sugar than Pepsi.

AHAHAHAHAHAHAHAHA I don't see how this pic belongs in this thread but still, very funny pic so thanks for sharing.
