This is one thing I don't understand, even though I know it must obviously work (to be clear, I'm not disputing it works. I just don't understand why/how). I know their purpose is to "remind you" Coca Cola exists, but unlike with junk removal services, you will never "need" Coca Cola and either you like it or you don't. People who like Coca Cola tend to drink it regardless of ads (some are addicts), and don't need the reminder. People who dislike Coca Cola won't ever drink it and the "need" will never exist in the future, unlike with junk removal.
So again, what's the rationale for these ads? Who needs a reminder that Coca Cola exists? I bet they are data-driven and their studies show that people do consume more soft drinks after seeing these ads everywhere -- I'm not disputing this -- but I really don't understand why it works.
Maybe the target is young kids exposed to these ads for the first time? But in general, the people in Coca Cola ads look like teenagers or in the 20-30 age segment, not kids.
(I know Coca Cola is terrible for your health and I keep telling myself I'll just stop drinking it. Maybe some day I will...)
Also, I think Coca-Cola is completely disgusting and you'd have to pay me quite a lot of money for me to agree to ingest the stuff, so maybe I'm not a very typical consumer. The fact that I know it's literally a poison to my body, in most plain sense (and probably yours too) doesn't help either :)
