If you want to step into the world of philosophy at any time period or in any part of the world, I highly recommend the podcast "A History of Philosophy Without Any Gaps" by Peter Adamson.
I'd also recommend "The Great Ideas of Philosophy, 2nd Edition" on audible. https://www.audible.com/pd/The-Great-Ideas-of-Philosophy-2nd...
For those interested in getting some basic knowledge about philosophy quickly I'd rather recommend Philosophize This! by Stephen West. The host isn't a philosopher by education but he seems to be very knowledgeable about the subject(at least to a layman such as me, feel free to correct this statement) and more importantly he focuses on the most important points that can be relevant to the average listener.
Also +1 for the Stanford Encyclopedia of Philosophy which has already been brought up by others ITT.
