This version of ELIZA looks to be recently produced, judging by print on the label.

ELIZA is an early natural language processing computer program created from 1964-1966 at the MIT Artificial Intelligence Laboratory by Joseph Weizenbaum.

Created to demonstrate the superficiality of communication between humans and machines, Eliza simulated conversation by using a "pattern matching" and substitution methodology that gave users an illusion of understanding on the part of the program, but had no built in framework for contextualizing events.

The most famous script, DOCTOR, simulated a Rogerian psychotherapist (in particular, Carl Rogers, who was well-known for simply parroting back at patients what they had just said), and used rules, dictated in the script, to respond with non-directional questions to user inputs. ELIZA was one of the first "chatterbots" and one of the first programs capable of attempting the Turing test.

Eliza was said to have inspired the interface of later text-based adventure games, and has been frequently referred to in popular culture ever since.
