Sorry what? Like, basically all businesses need to advertise, and unknown ones (i.e. small and new businesses) need to do this much more.

Coke will be fine if they stop buying TV spots (for a while, at least) but I'm pretty sure Linear/Datadog etc wouldn't be the size they are now without advertising.

> The main reason businesses need to rely on advertising to reach people is because people are already being bombarded by competitors.

Fundamentally, advertising is a way to tell potential customers you exist. Most people don't seek out new products, how do you think small businesses would grow in a world with no advertising?
