YouTube’s Right-Wing Stars Fuel Boom in Politically Charged Ads

On YouTube’s conservative airwaves, podcast hosts tout products that let people buy into the MAGA crowd: Republican Red Winery vintages for toasting the “silent majority;” Black Rifle Coffee for caffeinating gun owners; XX-XY Athletics for workout clothes symbolizing opposition to the “lunacy of the left social agenda.”The popularity of YouTube podcasts among conservatives is driving a boom in small businesses tailoring ads to their millions of listeners, paying hosts like Joe Rogan and Candace Owens to read out promotions in the hope that fans will place orders. The phenomenon has enriched both the hosts and YouTube, supporting further growth of the businesses using ideology to sell.

A Bloomberg analysis of host-read ads across nearly 1,000 videos from eight of the platform’s top right-leaning podcasters found that advertisers on the shows routinely tapped into political identity in marketing. At least one host-read ad with a political message appeared in 91% of videos reviewed.

The story behind RFK Jr. in Samoa's measles crisis has never been reported. He wasn't there to spread misinformation about vaccines (though he did). He wanted to study a "natural experiment" of unvaccinated kids. “I can’t imagine anything less ethical or more cruel.” www.nbcnews.com/news/us-news...

Experts saw Samoa's plunging vaccination rates as a crisis. RFK Jr. saw an opportunity.
New details show how Robert F. Kennedy Jr., then chair of an anti-vaccine group and now Trump’s pick for health secretary, sought to exploit a deadly vaccine accident.
