When do companies stop making parts for vehicles?

Just saw a post in another sub about a new vs old part for a 95 Intrepid and it got me wondering who still makes parts for a vehicle that old? Furthermore, when do car companies stop making parts for their cars? Here's for sake of example, I have a 2018 Frontier Pro4x, how much longer will Nissan produce parts for this make and model before I have to move over to the new frontier or another vehicle because I can't find new or "New" parts anymore?
