MPEG-4 Audio Layer (M4B) is the file format that stores audiobooks and podcasts, primarily those that are available on iTunes. The cool thing about this file format is that, unlike MPEG-Audio Layer III (MP3), M4B can store digital bookmarks. This feature allows readers to pause and resume later, just like a physical bookmark in a printed book!
The default program for opening M4B files is iTunes. For cross-platform access, VLC media player is a very dependable option that works on Mac OS X and mobile.
On Windows, several options are available. They include Windows Media Player, MediaMonkey, Winamp, and Helium Music Manager.
