awk comes from the initials of its designers: Alfred V.
Aho, Peter J. Weinberger and Brian W. Kernighan. The original version of
awk was written in 1977 at AT&T Bell Laboratories.
In 1985, a new version made the programming
language more powerful, introducing user-defined functions, multiple input
streams, and computed regular expressions.
This new version became widely available with Unix System V
Release 3.1 (SVR3.1).
The version in SVR4 added some new features and cleaned
up the behavior in some of the "dark corners" of the language.
The specification for
awk in the POSIX Command Language
and Utilities standard further clarified the language.
gawk designers and the original Bell Laboratories
designers provided feedback for the POSIX specification.
Paul Rubin wrote the GNU implementation,
gawk, in 1986.
Jay Fenlason completed it, with advice from Richard Stallman. John Woods
contributed parts of the code as well. In 1988 and 1989, David Trueman, with
help from me, thoroughly reworked

Circa 1995, I became the primary maintainer.
Current development focuses on bug fixes,
performance improvements, standards compliance, and occasionally, new features.
In May of 1997, Jürgen Kahrs felt the need for network access
awk, and with a little help from me, set about adding
features to do this for
gawk. At that time, he also

His code finally became part of the main
gawk version 3.1.
