While stacking on many hardbound physical books is pretty exhilarating, this is overpowered by digitalized book (e-book) trend nowadays.
Note! books are not dead. They just need to be digitalized.
With the improvements in recent eBook technology, readers have become more comfortable with "non-printed" books and there has been an increased demand for "Enhanced eBooks". The most dominant "enhancements" are the introduction of audio and video files into the "linear" story line of the book, something that cannot be done in a printed book.
