Not at all true. There’s a whole industry around measuring this (e.g. https://www.edo.com). A massive amount of money is spent on advertising for large companies. McD spend ballpark $3bn across the parent and franchisees, they want to make sure they get value.

You can ignore something actively but you are a still picking up on the message of it’s ubiquitousness. I think we have all had the experience of considering buying a {redacted} or something sometime after seeing and ignoring an add for one.

The worst part is, the value they get (monies) is not the same value you get (worse health all over).
