Why historical subjects need more explanation

For the same current-affairs subjects covered by Bilge Pumps, the solo-video estimate is up to an hour and a half of research and preparation, followed by about an hour and a half of recording with slides. Familiar current figures allow shorthand because the audience already knows who is being discussed. Donald Trump supplies that example, while a historical figure such as Philip II can require an introduction. Historical explanation therefore involves context that a current-affairs discussion can often assume. In this comparison, the time spent making one two-hour group podcast could allow two or three solo videos on the same subjects.
