Yep, I've been following that channel for the past few years. Lots of detailed (and often entertaining) information about the origins, production, and ultimate fate of many cartoons and toy lines from the '80s and other decades.The introduction to Voltron voiced by Optimus Prime himself Peter Cullen, and that guy got shittons of voice acting work and voice over credits to his name.
You might like these, a little behind the scenes history and they have done other shows as well.
