While readers the world over readily embraced e-books, the audio book did not receive much recognition at the outset. The ratio was 5 e-books to 1 audio book per reader.

Today, audio books are widely accepted and are fast gaining ground perhaps because of our modern busy lifestyles and advent of devices that make audio books more user friendly.

One great advantage of audio books is the convenience it offers. You can listen anywhere, anytime while doing a myriad of other things (talk of multi-tasking).

Audible, an Amazon company is offering a 30 day free audio book trial. See more details here: http://bookconvo.com/the-audio-book-revolution/
