The five most popular programming languages in the 1970’s were:
1970: Pascal
1972: C
1972: Smalltalk
1972: Prolog
1973: SQL
Pascal
The Pascal programming language was developed by Niklaus Wirth. It was created in 1968 but it wasn’t published until 1970. It was developed to provide the features other programming languages didn’t offer at that time. His main reason for developing Pascal was efficiently implement and run, to allow for the development of structured and well organized programs, and to serve as a tool to teach the important concepts of computer programming. The program was named after a mathematician named Blaise Pascal. It was used as the primary language in the Apple Lisa and for the Mac in the early years of the computer.
SQL
SQL, which is short for, Structured Query Language, was designed by an IBM research center in 1974-1975. The Oracle Corporation introduced it as a commercial database system in 1979, the first time it was introduced. It has been a favorite query language for the use of database management systems for the microcomputer and mainframes, but is being supported by the PC database.
C
C was created at the Bell Laboratory in 1972 by Dennis Ritchie. It was created for the purpose in designing UNIX.
Prolog
Was created from 1971-1973 and was distributed in 1974-1975. It was created not as a programming language on purpose but as a tool for processing natural languages specifically French. It was created by Robert Pasero, Philippe Roussel, Alain Colmerauer, and Jean Trudel.
Smalltalk
Developed in the early 1970’s, at the Xerox Palo Alto Research Center. It was created by Alan Kay, Dan Engalls, Adele Goldberg, and Dave Robson.
The five popular programming languages of the 1980’s are:
1983: Ada
1983: C++
1985: Eiffel
1987: Perl
1989: FL (Backus)
Ada
This program was designed in the early 1980’s and then enhanced in the mid 1990’s. Ada was designed to address the issues that arose from long-lived systems during testing/quality assurance, upgrades, and more.
C++
Created by, Bjarne Stroustrup. He began creating it in 1979. In 1983 the languages name was changes from C to C++. The goal behind C++ was to add object-oriented programming into the C language.
Eiffel
It was designed on September 23, 1985. Intended as an internal tool for newly created, ISE (Interactive Software Engineering). It was created by: Bertrand Meyer and Jean Marc Nerson.
Perl
Originally developed for text manipulation but is now used for many other things. It was created by: Larry Wall. It was released to usenet’s alt.comp.sources in 1987.
FL (Backus)
FL is short for Function Level. It was created by John Backus, John Williams, and Edward Wimmers at IBM Almaden Research Center, in 1989.
The five popular programming languages of the 1990’s are:
1990: Haskell
1990: Python
1991: Java
1993: Ruby
1994: PHP
Haskell
The motivation for designing the Haskell programming language was the need for a common language and for the language to be non-strict and purely functional. They designed it through a committee. This decision was reached in September 1987 in Portland, Oregon at the conference on Functional Programming Languages and Computer Architecture. The first version of the Haskell Report came out on April 1, 1990.
Python
The designer of the Python programming language released it in February of 1991. Guido Van Rossum is the designer of this program. He created it in order to correct some of the issues with the ABC language, which was an interpreted language. He also wanted to keep some of the features offered by the ABC language.
Java
The “Green Team” led by James Gosling was a small group of Sun engineers that believed the next wave in computing was the union of digital consumer devices and computers. They created Java by working around the clock in order to create it in 1991. The program was too advanced for the time and but was just right to use when the internet started to become popular in 1995.
Ruby
The Ruby language was created by Yukihiro “Matz” Matsumoto. He created it by blending different parts of his favorite languages to form a new language that would balance functional programming with imperative programming. His favorite languages were: Perl, Smalltalk, Eiffel, Ada, and Lisp. He publically released Ruby in 1995.
PHP
PHP was created in 1994 by Rasmus Lerdorf. It was originally used to track the visits to his online resume which grew to become capable of database interaction and more. He even released the source code for the PHP program to the public so that users could provide fixes for the bugs in the codes and to help improve it. Users were encouraged to do this and by releasing the source code it enables developers the ability to use it as they wanted.
