Kobo: Keeping Tabs on Best-Seller Books and Reading Habits

Last year, the release of the Hollywood adaptation of Gillian Flynn's 2012 novel "Gone Girl" propelled the book onto best-seller lists in several countries around the world. Millions of people bought it, but how many of them actually read it from cover to cover? The Toronto-based e-reading platform Kobo, which delivers digital books to 23 million people in 190 countries and is a competitor to Amazon Kindle, recently released statistics for 2014 that showed the best-selling books in the company's major markets and how frequently readers finished the titles they bought.
