Media hypes a lot of stuff that relates to high visibility topics. A new theory on cancer will get a zillion times more attention than millions still dying from TB or Malaria. It's Bemjamins at the end of the day. And, moreover it's not just media that creates hype, it's the stakeholders of theories, products who sell their ideas.
Cholesterol was so much hyped by industry, professionals and media for decades, and now it turns out neither HDL nor LDL are as good or as bad as they were made out to be. Science is and will always will be driven by Dollar.
So sad but true.
