VNS was only really known about inside Digital and by those who received a copy. However, there are a few notable references around the WWW.
The technology Watch entry for 19 Feb 1990 was included in “Archipelago” on 8 March 1990. Archipelago was an early form of FaceBook and began in 1988. The entry may be viewed here.

In 1995, the book Walking the World Wide Web: Your Personal Guide to the Best of the Web contained a section about Rob Hartill who was at Cardiff University at that time. This mentions “…the VOGON News Service that Rob created, which serves United Kingdom News daily”. The book can be found here.
The INTERNET Resource Directory for K-12 Teachers and Librarians, 95/96 Edition published in 1996 states that “News is available from the Vogon News Service as a daily news summary.” The book can be found here.
In 2009, a post by Bob Wyman on the Democracies Online discussion group said that “the Vogon News Service was, I think, one of the earliest uses of general computer networks to distribute news.”. Read the post here.
