When I am reading my e-books I always get facsinated in the highlighted notes that shows howmany people have underlined the same passage that I did. It might be a facinination with me but with Google and Amazon and other main players it is research.
I can guarantee there are a millions reasons they are interested in what the population is reading. So I found this TED Talk quite interesting in learning why the main players are reading. They have researched 500 billion words. Just wonder if your book could be one of them.
I found this humorous and informative. It’s worth listening to.
