ELI5: Why can't alcohol commercials actually show anyone drinking the product?
gpt
Legally, they can show it, however unofficially, it is banned based off previous agreements and  codes of conduct and network guidelines.

What does that all mean? It means while the govt hasn't specifically prohibited commercials  from showing alcohol consumption, among advertisers and tv stations/channels its an official (but not legally binding) agreement that they simply do not show people drinking alcohol in a commercial, if you want your commercial to air.  There is not much demand to change this, so it goes on.
