Yes, that's similar to the change from the type box to Lin-O-Type slugs.
Of course, the type box was a big advance over wood block, and we've
left the Lin-O-Type far behind in the past 50 years.

PDM/PWM is a big advance in modulation technique, adding a digital aspect
to analog, and we have hard drives rather than carts, all courtesy of 
solid state. I suppose you could also say there is quite a bit of digital 
in most of the analog consoles too. And, we use ISDN for remotes, but AM 
and FM have been the same since their respective inceptions while print has
gone from letterpress to molded plate rotary to offset rotary.

Look at the contrast to what's happened with computer technology while
radio has remained virtually static so far as the full system is concerned.
