Well, some people do collect those examples of early yellow journalism, so it could be a collection topic!
I, too, am often surprised that there is not more bias in newspaper reporting. You even see newspapers such as The Wall Street Journal breaking stories that are critical of conservatives, such as the birthday drawing DJT did to Jeffery Epstein.
My ex-husband, a business reporter, reads the WSJ all the time. He says their news reporting is strong and unbiased. But their editorial pages are extremely right-wing (probably in the more traditional sense; AFAIK they're not MAGA).
Looking back, I think PR is not very effective and I think the same of advertising as well. These influencers on the Internet seem to have better luck peddling wares.
I'm not sure. You'd think advertising must be somewhat effective, if only because brands pour so much money into it. Maybe less so now, though, because people stream shows without TV ads, print is dwindling, and online ads are not considered as effective.
According to google, glamorous lifestyle influencers are being replaced by "expert" influencers. I suppose they mean, like, those doctors who tell you whether this or that remedy is effective, or behavioral coaches who tell you what small things make people like you or dislike you. Those are a lot of what I see these days, but of course they're not really intended to sell massive quantities of any particular brands.
I hope PR continues to be effective, though, because my younger son works in that industry. "The dark side," we call it in newspapers. It's financially rewarding, anyway. At 30, he's already making about $15,000 a year more than I made at the pinnacle of my journalism career.
