There's a lot of interesting historical context here in this interview with Don Figlozzi, possibly the first guy to be hired by a TV station to draw animation for television. (Now to my mind, there had to be someone doing something at WCBT or WNBT at that point in 1949 that was animated, but Mr. Figlozzi appears to be the first on-staff animator.)
