(written from a Production point of view)
StarTrek.com is the official website for the entire Star Trek franchise. The site features an extensive database, episode guide, interviews, news feed, fan quizzes, new articles, videos, retail shop, event calendar, and other exclusive content. It is produced by CBS Entertainment for CBS Studios Inc., a division of CBS Corporation.
Star Trek ContinuumEdit
In the Voyager Season 1 DVD documentary short, "Launching Voyager on web", the history of StarTrek.com was spotlighted. Using a modified screen capture from the "Parallax" episode, a computer shows the website on its screen. The site and its structure were also briefly discussed in the TNG Season 2 DVD special feature, "Mission Overview Year Two - Gene Roddenberry".
On 14 December 2007, it was announced that the entire production team responsible for StarTrek.com had been laid off, effective immediately. The lay-offs came as the result of "restructuring" at CBS Interactive. (X)
Site Relaunch Edit
After an extensive period of inactivity (which included the period in which 2009's Star Trek was produced and released), CBS Interactive announced on 5 May 2010 that a new version of StarTrek.com would launch in the summer of 2010.  
The newly-designed site was created by Funny Garbage and was launched as a beta version on 14 July 2010. It retained much of the content that was previously displayed on the site and now featured news headlines from other major Star Trek sites, fan contributions, and full-length episode streams of Star Trek: The Original Series and Star Trek: Enterprise (geo-restricted to the United States). 
Star Trek Shop Edit
Through its online Star Trek Shop, the site has retailed many licensed Star Trek-related items including novelties, collectibles, toys, artwork, housewares, jewelery, electronics, and clothing. All products are sold on the site by Delivery Agent, Inc. of Crozet, VA, USA.
