I always thought about this, but not about Coca-Cola, since people actually need to want to buy it to acquire it, but Visa and Mastercard have huge advertising budgets, notably for events like the World Cup and the Olympics, and I never met someone who actively pursued a specific card flag when getting a new card and instead just get whichever their bank has to offer.

But then someone at the bank has to decide between Visa and Mastercard.

And this persons surely thinks "ok, the conditions are roughly the same, what is going to make sure none of my clients even bother to ask why we chose this".

So the bank picks something they know that for sure their clients won't question, and here you are. Even if a newer provider emerged with better conditions, they probably wouldn't pick it because they don't want to deal with the inevitable questions.

But they're not getting Amex or Discover.

Plus, thanks to all the ads they might be pulling out that Visa or Mastercard when they pay for something, rather than using cash. Or they might use the Visa or Mastercard online rather than Paypal. etc etc...
