# Programming Language Design and Implementation (conference)

The Programming Language Design and Implementation (PLDI) conference is an annual computer science conference organized by the Association for Computing Machinery (ACM) which focuses on the study of algorithms, programming languages and compilers. It is sponsored by the SIGPLAN special interest group on programming languages.
In 2003, the conference was given an estimated impact factor of 2.89 by CiteSeer, placing it in the top 1% of computer science conferences.

## History

The precursor of PLDI was the Symposium on Compiler Optimization, held July 27–28, 1970 at the University of Illinois at Urbana-Champaign and chaired by Robert S. Northcote. That conference included papers by Frances E. Allen, John Cocke, Alfred V. Aho, Ravi Sethi, and Jeffrey D. Ullman. The first conference in the current PLDI series took place in 1979 under the name SIGPLAN Symposium on Compiler Construction in Denver, Colorado. The next compiler construction conference took place in 1982 in Boston, Massachusetts. The compiler construction conferences then alternated with SIGPLAN Conferences on Language Issues until 1988, when the conference was renamed to PLDI. From 1982 until 2001, the conference acronym was SIGPLAN 'xx. Starting in 2002, the initialism became PLDI 'xx, and in 2006 it became PLDI xxxx.
