Think of Netflix's "ta-dum", Tiffany's patent colour, Coca-Cola's red or Nike's swoosh. Then think if you recall anything more. Do you need to?
How many brands do you use? How many are ones you truly care for? From these, for how many can you recall advertising? I am sure the answer would be a single digit. But there will be many more brands which you can identify, at a glance, without any other prompting. Just their design, packaging, colour, smell, and more, will pop them up in your memory. That is important.
