I think that's pushing the boundary on what can be considered advertising these days. It's a question of choice. Advertisements are foisted upon (mostly) unwilling viewers to convince them to buy things they don't want or need, or
at least to cause them to make a choice based on brand identity rather than a rational evaluation of the value provided. This is bad.
What you're talking abut is something else entirely. If I'm watching something on Hulu, and the show stops to show me an ad for a Marvel movie coming out in a couple months, that's intrusive. If I deliberately go to YouTube to watch the trailer, that's a free choice. They're such completely different experiences from the user's point of view that it's a misnomer to refer to both as "advertising".
Likewise, my parents have solicited mailers from local groceries because they want to know what vegetables are in this week. There are all sorts of websites and other mechanisms for letting people know about events and opportunities going on in their area. Me sitting down to watch some sports or something and getting bombarded by ads (by Arby's, not a "local farm") is not the same situation.
If you want a bright line, imagine a world with no profit motive. Would we still have movie trailers and fliers to let you know about local farm produce? I think so. Would there still be television advertisements and lies about VPN services on YouTube videos? Obviously not.
