The concept of digital advertisement was unknown to Humans in ST universe until Ferengis brought an example to Federation Starbase Deep Space 9 in 2372, so that’s one divergence between our universe and Star Trek version of it.

Off topic, but Deep Space 9 was not a federation starbase. It was a Bajorian Republic station under Federation administration following the Cardassian withdrawal.

S/he's very sorry for misusing "starbase", s/he means a station.

Oh I assumed it was under sole Federation control from the prefix “Deep Space”, wasn’t aware it was under Bajorian ownership. I stand corrected.

Sao Paulo did away with public advertising for a couple decades.

I believe it is creeping back in now. But it can be done.
