Amazon Kindle books sometimes receive ebook updates that the publisher or author pushes out. The Amazon Kindle e-reader has a reporting feature in digital books for spelling mistakes that are automatically sent over and often revised. The ebook cover art will be updated to generate interest when a book is made into a movie. An example of this is Andy Weir's The Martian; the old book was orange and had an image of an astronaut, but the updated one has a massive face of actor Matt Damon. Amazon is not the only company to update ebooks; Google Play and Kobo
