LV: In the old days, ISC also stood for Interative Systems Corp., one of the early commercial Unix vendors. They sold IS/3, based on ATT's System III, with some specialty hardware text terminals for interacting with the system.

Description

Stu:

I have recently switched my license preference from BSD to ISC (Internet Systems Consortium).

The ISC license is (in my words) a modern BSD license. It's also smaller.

In their words: It is functionally equivalent to the 2-clause BSD licence, with language "made unnecessary by the Berne convention" removed.
