This page shows the history of businesses strongly tied to APL or other array language implementation. Many other commercial vendors have implemented APL at some point.
By dialect
Here families of dialects are grouped together: IBM APL includes APL\360, APL.SV, and others; APL*PLUS includes APL+Win and APL64; and SHARP APL includes SAX.
Entries in parentheses indicate a change in ownership of the array language developer. Those marked with an asterisk indicate new employee-owned companies.
