Elle Griffin: In 2020, “only 11 books sold more than 500,000 copies — which is paltry when you consider that the 10 best-performing Netflix films last year saw more than 68 million views — in their first month. If even our best-selling books hit only a fraction of the audiences of best-performing films, books as a medium just don’t have an audience — or rather, they have a very niche audience.”
