What printing technology ultimately superseded woodblock printing?

Movable metal type, usually molded from lead.

Hot metal Linotype machines eventually automated the process of setting individual lines of molded lead type for printing, eliminating the process of manually resorting the type back into the boxes after the print job was done (the used type could simply be melted for reuse).

The Linotype was also eventually superseded when high speed rotary presses came into use.
