One thing you might be missing, and the reason that widely-viewed events are so valuable as ad space, is that one function of ads can be to create common knowledge among the audience of how other people might see the product.
For example, Corona beer has a beach vibe. They don’t just want you to know that it has a beach vibe, they want you to know that other people know that it has a beach vibe. That way, if you are going to a party and want to bring something that has a beach vibe, you’ll reach for Corona because you want to be seen by others as bringing the beach vibe. This is why ads on widely-viewed broadcasts like sports games disproportionately (tho not exclusively) focus on products that are consumed socially or in public rather than privately.
This is not true, the entire area of Tort law (especially negligence law) is highly developed in English speaking countries, and is a series of elaborations on “take reasonable care to avoid harm to others.”
