I rarely watch regular TV but when I do it’s immediately noticeable how much louder the commercials are than the program you are watching.
I’m sure the advertising industry has done extensive research on this and came to the conclusion that it grabs your attention but it never works in my house. Instead of getting positive attention it ends up everyone screaming, “turn it down”.
Product sales are the same, you can’t scream or spam your way to become a market leader. Instead, it takes word of mouth, trust, and getting people interested. Once you do those the rest will come.
