What things has advertisement and marketing "destroyed"?

Running shoes in general to me have really brought down running in a way. The amount of money and thought going into something that to me almost is hardly beneficial and has not magically made people run faster or fix injuries.

My other would be supplements. In particular people who are into working out. I find most are just so over the top and ridiculous saying all this bullshit. I tried it to a degree and in the end I realized you can get what you need from real foods.

I can only speak for my experiences. What things do you think have degraded something in one way or another?
