A new report from CNN finds that a search for "vaccine" on Amazon yields a results page dominated by anti-vaccination books and movies. Some include sponsored posts, or ads for the anti-vaccine content. CNN notes that a number of anti-vaccination movies are also available for free viewing on Amazon's streaming video service Prime Video.
Why it matters: Amazon has until now avoided the "fake news" drama that its rivals Google and Facebook have faced, in part because it's considered a hub for products, not a platform for ideas. This example underscores the fact that any platform that takes contributions from the public can be susceptible to manipulation, which can lead to the spread of misinformation.
