• 1943 - ENIAC coding system, machine-specific codeset appearing in 1948.^[2]
• 1949 - 1954 — a series of machine-specific mnemonic instruction sets, like ENIAC's, beginning in 1949 with C-10 for BINAC (which later evolved into UNIVAC).^[3] Each codeset, or instruction set, was tailored to a specific manufacturer.

• Simula, invented in the late 1960s by Nygaard and Dahl as a superset of Algol 60, was the first language designed to support object-oriented programming.
• C, an early systems programming language, was developed by Dennis Ritchie and Ken Thompson at Bell Labs between 1969 and 1973.
• Smalltalk (mid 1970s) provided a complete ground-up design of an object-oriented language.
• Prolog, designed in 1972 by Colmerauer, Roussel, and Kowalski, was the first logic programming language.
• ML built a polymorphic type system (invented by Robin Milner in 1973) on top of Lisp, pioneering statically typed functional programming languages.
