Audible offers two of its original audiobooks free every month

This is clearly meant to sweeten the pot for Audible subscribers, but it also gives the service’s exclusive material a better opportunity to shine. You no longer have to give up on a must-read thriller or tell-all just to take a chance on one of Audible’s own works. That, in turn, could give Audible a better idea of which Originals are working and help it produce more in that vein.
