The last specials on the more recent Presidents such as Lyndon Johnson for example didn't have prologues like what you see above for the 1st President George Washington. Other than these prologues the programs contained at least 3 or more hours of viewer calls, vignettes, and discussions with not only historians but also with the descendents of these Presidents as well.
It helped spark my interest in studying the Presidency. It wasn't always considered a post that we often call "Leader of the Free World". This office had to evolve like anything else here in the United States. The men who have held office helped it evolve.
I look forward to seeing more of this in the future. In fact C-Span uploaded a prologue for John Adams onto YouTube recently. Of course if you want to find the full programs as their aired over a decade a go just visit C-Span's video archive or check C-Span's schedule see if they'll air on TV in the future.
