Google Groups is a service from Google that provides discussion groups for people sharing common interests. The Groups service also provides a gateway to Usenet newsgroups via a shared user interface.
Google Groups became operational in February 2001, following Google's acquisition of Deja's Usenet archive. Deja News had been operational since 1995.
Google Groups allows any user to freely conduct and access threaded discussions, via either a web interface or e-mail. There are at least two kinds of discussion group. The first kind are forums specific to Google Groups, which act more like mailing lists. The second kind are Usenet groups, accessible by NNTP, for which Google Groups acts as gateway and unofficial archive. The Google Groups archive of Usenet newsgroup postings dates back to 1981. Through the Google Groups user interface, users can read and post to Usenet groups.
In addition to accessing Google and Usenet groups, registered users can also set up mailing list archives for e-mail lists that are hosted elsewhere.
The Deja News Research Service was an archive of messages posted to Usenet discussion groups, started in March 1995 by Steve Madere in Austin, Texas. Its powerful search engine capabilities won the service acclaim, generated controversy, and significantly changed the perceived nature of online discussion. This archive was acquired by Google in 2001.
While archives of Usenet discussions had been kept for as long as the medium existed, Deja News offered a novel combination of features. It was available to the general public, provided a simple World Wide Web user interface, allowed searches across all archived newsgroups, returned immediate results, and retained messages indefinitely. The search facilities transformed Usenet from a loosely organized and ephemeral communication tool into a valued information repository. The archive's relative permanence, combined with the ability to search messages by author, raised concerns about privacy and confirmed oft-repeated past admonishments that posters should be cautious in discussing themselves and others.
While Madere was initially reluctant to remove archived material, protests from users and legal pressure led to the introduction of "nuking", a method for posters to permanently remove their own messages from search results. It already supported the use of an "X-No-Archive" message header, which if present would cause an article to be omitted from the archive. This did not prevent others from quoting the material in a later message and causing it to be stored. Copyright holders were also allowed to have material removed from the archive. According to Humphrey Marr of Deja News, copyright actions most frequently came from the Church of Scientology.
The capability to "nuke" postings was kept open for many years but later removed without explanation under Google's tenure. Google also mistakenly resurrected previously "nuked" messages at one point, angering many users. "Nukes" that were in effect at the time when Google removed the possibility, are still honored, however. Since May 2014, European users can request to have search results for their name from Google Groups, including their Usenet archive, delinked under the right to be forgotten law. Google Groups is one of the ten most delinked sites. If Google does not grant a delinking, Europeans can appeal to their local Data Protection Agencies.
The service was eventually expanded beyond search. My Deja News offered the ability to read Usenet in the traditional chronological, per-group manner, and to post new messages to the network. Deja Communities were private Internet forums offered primarily to businesses. In 1999 the site (now known as Deja.com) sharply changed direction and made its primary feature a shopping comparison service. During this transition, which involved relocation of the servers, many older messages in the Usenet archive became unavailable. By late 2000 the company, in financial distress, sold the shopping service to eBay, who incorporated the technology into their half.com services.
By 2001, the Deja search service was shut down. In February 2001, Google acquired Deja News and its archive, and transitioned its assets to groups.google.com. Users were then able to access these Usenet newsgroups through the new Google Groups interface.
By the end of 2001, the archive had been supplemented with other archived messages dating back to May 11, 1981. These early posts from 1981-1991 were donated to Google by the University of Western Ontario, based on archives by Henry Spencer from the University of Toronto. A short while later,[when?] Google released a new version that allowed users to create their own non-Usenet groups.
For several years from May 2010 onward, Google incrementally changed the layout of the web search results pages, often degrading the discoverability of the site itself as well as its usability and functionality.
On February 13, 2015, a Vice Media story reported that the ability to do advanced searches across all groups had again become nonfunctional, and to date, Google has neither fixed nor acknowledged the problem. The researcher interviewed stated, "Advanced searches within specific groups appear to be working, but that's hardly useful for any form of research--be it casual or academic."
The late Lee Rizor, also known as "Blinky the Shark", started the Usenet Improvement Project, a project which is highly critical of Google Groups and its users. The project aims to "make Usenet participation a better experience". They have accused Google Groups of ignoring an "increasing wave of spam" from its servers and of encouraging an Eternal September of "lusers" and "lamers" arriving in established groups en masse. The Usenet Improvement Project provides several killfile examples to block messages posted by Google Groups users in several newsreaders.
Slashdot, Vice and Wired contributors have criticized Google for its unannounced discontinuation of the Google Groups Advanced Search page and the ability to perform advanced searches across all groups, leaving it nearly impossible to find postings without either knowing keywords from them that are unique across Google Groups' entire multi-decade archive of posts, or else knowing beforehand which newsgroup(s) they were posted in. And other commentators have since noted that even many simple searches across all groups repeatably fail to return correct results.
Google Groups has been blocked in Turkey since April 10, 2008 by the order of a court there. According to The Guardian, the court banned Google Groups following a libel complaint by Adnan Oktar against the service. Google Groups was the first of several websites to be blocked by the Turkish Government in rapid succession solely for including material that allegedly offended Islam.
