It's not propoganda. It's the market responding to incentives and understanding that society has an appetite for it. The premise that "they" push things on society is silly. Marketing is all about responding to market incentives and titiliating people. Blonde hair and big boobs was the 70s version of this. Marketing execs didnt invent blondes with boobs, they recognized sex sells.Why, just because you don't like the truth being told? Fact is, this is propaganda, not advertising and someone is behind it. Probably white men with a disgusting fetish.
It doesn't make even economic sense because most latins and asians, in comparison, come from stable two-parent homes, with good two-parent incomes. You would think if ads wanted to hit dual targets of increasing market share and diversifying, it would advertise more to these two groups by using more of them in ads, as they have a much better economic and educational foundations and buying power. But no, these ads just seem to want to just focusing on the blacks.
In any case, in those ads above, white women who were that attractive and established, if they did decide to date interracially, are almost certain to go for a latin partner or an asian partner, and almost certainly not a black one. That ad of the white women lying in bed with the black guy looks so ridiculously sstaged and will likely alienate whites and even asians and hispanics. I mean, seriously, why would a compalny want to pi$$ off the very people with the financial power to buy their products? As I said, makes no sense, just agenda-pushing.
The 1980s was all about the jingle. The jingle was intended to create earworms and go "viral" getting people to sing it and create earned media.
In the 90s it was "edgy" embracing the angst of grunge. Advertising companies didnt push grunge on the people but companies felt they had to have authenticity and grit to gather brand loyalty.
2000s introduced google and internet ads, marketing people didnt push the internet on people. Google was able to perform targeted advertisement to follow the specific habits of the person.
The 2010s saw the boomers start to retire and advertisers targeted those incomes by feeding them ads for prescription *******, reverse mortgages, etc.
This current trend is responding to Gen Z and Millenials who pride themselves on their social awareness and anti-racist beliefs.
Basically the only thing nefarious about this is capitalism.
