00:00Have you always wondered what happened to the B battery?
00:03Back in the 1920s, 30s and 40s, B batteries were common.
00:08They were used to power portable vacuum tube radios.
00:12But then along came the transistor and electronics got much smaller.
00:16So while the B battery said,
00:18I powered the golden age of radio,
00:21the transistor said,
00:22I fit in a shirt pocket.
00:24And it wasn't long before the B battery was sent off to the portable power source retirement home.
00:28The B battery was basically the middle child of the battery family,
00:33neither small enough nor big enough to be practical.
00:36It simply fell victim to obsolete technology.
00:38And it had absolutely nothing to do with some shadowy organization known as big battery.
00:45Okay.
00:46Always wondered stream it now, wherever you get your podcasts.
