Just imagine, if everything that used transistors today was actually powered by beautiful vacuum tubes of old. Control yourselves, steampunkers, this 1942 RCA doc "Electrons on Parade" may blow your vintage thought fuses.

And, also, forget Twitter—I need the narrator of these videos to just follow me around and annotate the minutiae of my life in that glorious 1940s radio voice. Now that would be entertainment.
