The following array family programming languages, and papers describing languages, have had a major influence on commonly-used APLs.
| Year | Event |
|---|---|
| 1962 | A Programming Language describes Ken Iverson's notation |
| 1966 | APL\360 completed and used within IBM |
| 1968 | APL\1130 released as an IBM Type-III Library |
| 1970 | APL*PLUS is offered by IPSA and STSC as part of a time-sharing service |
| 1971 | "A Generalization of APL", Jim Brown's Ph.D. thesis, describes a nested APL which later becomes the basis of APL2 |
| 1973 | APL.SV introduces shared variables |
| 1976 (approximate) | SHARP APL splits from APL*PLUS |
| 1981 | NARS is the first nested APL, and implements ideas from Operators and Functions |
| 1981 | SHARP APL adds boxes to the flat array model |
| 1983 | Rationalized APL, a paper on Iverson's latest thinking on APL, includes the Rank operator added to SHARP APL later that year |
| 1983 | Dyalog APL, based on NARS and the to-be-released APL2, is released |
| 1984 | APL2 is IBM's take on nested array programming |
| 1985 | A is Arthur Whitney's APL, the first to be based on leading axis theory |
| 1987 | A Dictionary of APL describes a precursor to J |
| 1988 | A+ adds a GUI to A and replaces it |
| 1990 | J is Ken Iverson's new array language, with ASCII characters and based on leading axis theory |
| 1992 | K ("K0"), Arthur Whitney's list-based language, first becomes available |
| 1997 | Dyalog APL adds dfns |
| 2006 | NARS2000, a successor to NARS, is released |
| 2009 | VisualAPL is the first .NET-based APL, but soon stops development |
| 2010 | APL#, a .NET-based language, is released by Dyalog Ltd., to be abandoned in 2012 |
| 2013 | GNU APL is the first fully scriptable APL |
