Although as time goes by things are becoming even more dire for the influencer marketing industry since the average joe find these influencers even less and lesser trustworthy, given the fact that the public's already made aware of just how much money these guys make from endorsement and from adsense and the lengths that some of them go to just to get that bag. Memes are becoming more and more mainstream thanks to short-form content made evident by the fact that even large-scale companies which built this "serious no bullshit" atmosphere around them's starting to post ads riddled with memes and weird shit. We're living in very absurd times.
I would say that it's getting harder to become an influencer, average Joe still believes what his influencer tells him. Now many influencers try to leave impression that they are not the paid ones and they are the only one who tells the truth but in reality most of them are still paid.
I would call the modern trend dumbcore instead of weirdcore because people value stupidity over smartness. NFTs and the value of some of them prove that the more dumb thing you make, the higher the value of this thing will be. Bitcoin Ordinals spam attack proves again how many people try to make dumb things to gain money because with smart and good things they financially fail.
So in my opinion marketing in the digital era is more efficient by relying on social media rather than TV and radio or others.
It still depends on your audience. If you are selling the product for young and between 30-40 years old people, then advertisement on social media is much cheaper and brings more result but if you sell the product for mid-age people (40-60 years old), then TV or Radio, depends on the country and the city, might be better than advertisement through social media.
