I'm so happy to read this, I've been thinking about this question for a while now, and I think it would help a lot:

Big companies where revenues are based on marketing would collapse, the market fragments (which is good), smaller companies are created instead, better diversity of local products and services. Better wealth distribution. More money for the government, hopefully better public services.

With less flashy products and services, people have a better purchasing power, even considering they'll have to pay for services they use, like reviews. Review companies would need strict controls to be put in place against corruption.

It would probably also change a lot of nonsensical landscapes (ex: sports)

Advertising is evil.
