Prof Peter Adamson's History of Philosophy without Any Gaps -- it is an extremely thorough podcast series that covers the histories of Western, Indian, and African philosophy (it has taken many years to get this much covered!). I believe Chinese philosophy is coming soon. In Western philosophy, he has gone from pre-Socratic philosophy in ancient Greece all the way to the Renaissance so far. He covered Arabic philosophy in the medieval period, too.
