Overview
Through its various activities beginning in 1978 Software Research (SR) has interacted with the software testing and quality control community in a variety of ways, combining outbound communications (TTN, QTN, QMM, and the eValid BLOG) and community activities like Quality Week/Quality Week Europe. Below are details about the progress of this activity.

• Testing Techniques Newsletter (TTN)
  TTN was a printed and mailed newsletter. Here is a digitized version of TTN from 1978 through 1995:

  Testing Techniques Newsletter (TTN) [~80 issues]

  The first TTN (May 1978) and a few issues thereafter were produced by simple typescript and later automated DTC-printed as right-ragged (non-justified) material. Later, from May 1980, TTN was produced right-justified (from an early Office Unix machine). Harc copies of TTN were mailed to subscribers at no charge via USPS.

  Early editions used SR's P.O. Box 2432, rather than (A) 1874 Greenwich Street or (B) #9 1st Street or (C) 580 Market Street.

  TTN, V6, N1, February 1983 This was the last "monthly" version. The next one issued, V6, N2, is called "Spring 1983" and after that monthly issuance ceased.

  After TTN, V9, N1, Summer 1987, we used (D) 625 Third Street, the first time the office street address was used.

  TTN, V13, N3, Fall 1991. We Converted to new format, carried forward in this format through Fall 1995. The final USPS mailed issue was V18, N2 (Fall 1991).

  The last printed copy was in mailed in 1995, but the electronic e-mailed TTN, Online Edition, January 1994, and/or web-based version continued until the end of 2005.

• Quality Techniques News (QTN)
  From 1994 and continuing until 2005, TTN was a monthly online edition only.

  After 2000 TTN was changed to Quality Techniques News (QTN) to reflect the greater breadth of coverage the newsletter achieved.

  Here is the complete contents of all of the TTN/QTN Online issues:

  TTN/QTN Online Index: 1994-2005

  The December 2005 issue declares QTN's Final Issue in favor of QTN as a blog.

• Quality Management Monthly (QMM)
  QMM was a short-lived paid-subscription superset of TTN. Here is the complete content:

  Quality Management Monthly (QMM), April 1982 -- May 1983, [14 issues]

  Some articles in QMM were expanded versions of what was in TTN and TTN articles in that era often referred to expanded versions available in QMM. The attempt to sell subscriptions did not succeed and QMM was discontinued.

• eValid BLOG
  From 16 July 2007 onward, the eValid BLOG replaced QTN. Here is the BLOG reference, which continues to the present.

Situation At January 2022
From May 1978 to January 2022 makes this ~44 years of communication into the greater "software testing and software quality community". However, the Google Groups sites for Selenium, WATIR, and WebDriver have largely taken over the central-communications role.

It is worth mentioning that the old Usenet system, of which comp.software.testing was a part. was also central to this community; that newsgroup still exists as a Google Group: Comp.Software.Testing.
