I like Tom's idea , the cheaper the better for the Bean counters and a kinda big triode VS a smaller diode wouldn't fly . While the TV's screens themselves kept getting bigger , smaller & cheaper circuitry was the driving force behind such design changes since the beginning of mass market electronics . Yep , price gets my vote .
