This influencer nonsense described here is gross and fake compared to that. What would a genuine, face-to-face advertising campaign look like nowadays?
Honestly the Tupperware parties weren't great for the company either; while it kept an exclusivity to the brand it also severely limited their client base. You had to know someone who hosted them, or knew someone who knew them. Then they had to take time away from things they have or want to do to go be advertised to. They ended up social when they started because you invited your friends and neighbours, but after you exhausted them you're just a door to door salesperson.
Worse than that, they feel entitled to them, to the point that the actual expectation of having to pay for something that requires effort to maintain is treated as an insult.
