Let’s answer:

1. Generally speaking, the products that appear in TV series or movies are basically sponsors and advertisements. Especially the food, food, and drinks used by the protagonist are basically advertisements. Of course, there is another situation where this is not the case, such as the Microsoft system in "The Wandering Earth". This is not an advertisement. Like the sound from "Independence Day 2", hello, cool dog, no doubt an advertisement.

2. If the props that must be used in many TV dramas are not sponsors or advertisements, the trademark names will usually be removed. Like mineral water, beer and so on.

ICBC sponsored "Transformers 4", so there is a plot where an ICBC card appears. Of course, some plots require banks, but it is not necessarily an advertisement. Some of these on JD.com and Tmall are sponsored advertisements. Of course, they are occasionally used as plot needs. Things that appear in TV series cannot be generalized and need to be observed by the subject himself. It's actually quite interesting to look for ads. I recommend "Independence Day 2", which is probably the science fiction film with the most ads.
