(written from a Production point of view)
DVD (short for Digital Versatile (or Video) Disc) is a digital standard-definition (SD) optical disc home media entertainment format. Developed in the early 1990s by Sony and Philips, the digital format gives higher resolution picture and sound than the Betamax or VHS magnetic video tape, and allows for special features to be added alongside the main feature. These advantages over VHS ultimately led to the decline of that format, as indeed it did for the contemporary optical disc format contenders VCD (ironically also from Philips) and LaserDisc for similar reasons.
Despite the fact that a consumer needed to operate a new playback devise to access a DVD, the format became a breakout success from the time it was introduced. This was, aside from the intrinsic picture and sound quality, in equal measure due to the physical qualities of the new format. Ease of disc handling and accessibility of a movie or television production on the disc was greatly enhanced over the more cumbersome magnetic video tape, whereas the physical size of the medium was only a fraction of that of a video tape with both disc storage capacity and longevity being far superior to that of a video tape, which was susceptible to mechanical wear and tear, causing picture and sound quality to degrade over time contrary to the constant quality of a DVD (provided a disc was properly stored as an optical disc is moist and natural light sensitive, something a magnetic tape is also and in even greater measure susceptible to). For collectors, such as those of Star Trek, size and greater disc storage capacity meant that substantial physical space savings could be realized in their homes. Whereas a full season of a Star Trek series comprised of around thirteen two-episode video tapes, the series on DVD would only take up six or seven of the much smaller four-episode discs; a full seven season series of, for example, Star Trek: The Next Generation on DVD, took up the same, or, depending on the packaging, even less space than one of its respective seasons on VHS.
Adoption of the new format was accelerated as it also used the same dissemination method that had made its magnetic tape predecessor so successful, the video rental circuit. Most rental companies also carried basic players, customers, not yet owning one of their own, could borrow to watch their rented products, strongly aiding the acceptance of the format. However, it also made the rental circuit increasingly redundant, when prices of both discs and players started to drop to the point where the video rental circuit had all but disappeared. The video tape format did not disappear overnight though, as it continued to exist a while longer as television recording devise (in the process serving to preserve many Star Trek TV specials not included on any of the later home media formats, with many of them later posted on YouTube), a feature not carried by the DVD format, until digital alternatives became available in the 2000s. However, as a prerecorded home media entertainment consumable, the era of the magnetic video tape format was over, the moment the DVD became widely available. In this, the DVD format has also greatly benefited from the rise of the online retailer in the same era, of which Amazon.com was one of the more conspicuous ones.
A commercial success story for the better part of two decades in which it became a near universal standard and home presence, the DVD went into decline itself with the advent of the even more superior Blu-ray Disc format in 2006 – though its acceptance was hindered by the universal success of its predecessor, acknowledged as such by Hollywood studios, who as of 2019 still concurrently release their productions in both formats, and Blu-ray player manufacturers whose products are virtually all capable to play DVD discs as well. However, both also started to suffer more noticeably from the more recent, early 2010s, advent of the increasingly popular digital video-on-demand streaming services as provided by such companies as, most conspicuously, Netflix.
DVD releases are divided into separate regions, to restrict the areas specific discs can be played. The following is a guide to the regions and which areas of the world they relate to:
|"Region free" releases|
|1||US, Canada, US territories|
|2||Japan, Europe, South Africa, Middle East (including Egypt), French Guiana|
|3||East and South East Asia (including Hong Kong and Macau)|
|4||Oceania, Central and South America, the Caribbean|
|5||Russia, former Soviet republics, the Indian sub-continent, Africa, North Korea, Mongolia|
While customers and collectors in particular frowned upon the geo-restricting format, there had been valid business reasons involved for its usage; at the time of the introduction of the DVD, the near simultaneously worldwide roll-out of a new Hollywood production as currently employed, was not yet in place, meaning a production (and therefore its resultant home media format) premiered in different places at different times. Japan and other eastern Asian countries, for example could habitually lag for almost up to a year behind the USA where theatrical features were concerned. The geo-restriction was intended as a protection measure for not only theater owners and broadcasters who still had to show these productions in the lagging territories, but also for local branches of home media distributors, such as CIC Video, justifying their existence. In the latter case, these local branches enjoyed a certain measure of autonomy in regard to regional marketing strategies, often resulting in regional differences in DVD releases, especially where the in-, or exclusion of special features was concerned, not rarely to the frustration of collectors located in other regions, those of Star Trek included.
DVD player manufacturers were enforced by Hollywood studios to build these restrictions into their marketed players as well – either by software or hardware – , so that for example a Region 2 player was only able to play a Region 2 disc, that is in theory at least as less scrupulous dealers were able to quite easily circumvent (whether or not surreptitiously aided by the manufacturers themselves as software patches in particular were regularly leaked on the internet) the restricting player measures for their customers. Geo-restriction became a major contributing factor to the pervasive problem of piracy – combating this having ironically been one of the main reasons for the employment of the region encoding format – , especially in regions 3, 5 and 6, and one of the reasons why the non-restricted VCD format held out for so long in these regions, long after it went defunct elsewhere in the world. The VCD had in the intervening years become the medium of choice for pirated copies in these regions, which in turn, alongside the proliferating (illegal) digital dissemination possibilities through the internet, has forced Hollywood to eventually adopt the near simultaneous worldwide roll-out format for both their productions and resultant home media formats.
This in turn has led to the increasing redundancy of geo-restricting the home media releases, as is evidenced for the Blu-ray successor. While still employed – with keeping local distributors alive as the only remaining rationale – , more and more regular releases are in effect becoming region-free (regardless of what the packaging might state as was the case with the recent Star Trek: The Compendium Blu-ray release) with contents standardized for the entire world. This however, is not the case for the DVD where the geo-restriction format is still upheld in full force, conceivably as additional means for production companies to entice consumers further to make the switch from DVD to Blu-ray.
History of Star Trek on DVD Edit
Star Trek DVDs first emerged in 1998 in Region 1, when Paramount Home Video began releasing basic, "vanilla" releases of the first nine Star Trek films – usually containing the film and its associated trailers only. The films were released in a mostly reverse chronological order, starting with Star Trek: First Contact. Star Trek: Insurrection saw release during this time (slotting in between Star Trek V: The Final Frontier and Star Trek IV: The Voyage Home), and the last prime universe film, Star Trek Nemesis, was released in 2003. The majority of these releases included very limited special features, typically only comprised of theatrical teasers and trailers, though televised franchise promotional production shorts were, one each, added on Insurrection and The Voyage Home, whereas Nemesis even featured a modest selection of especially produced special features.
As it turned out however, more Nemesis special features had been produced for the hereafter mentioned "special edition" film collection (which by the time of the Nemesis "vanilla" release was already up and running), but part of the remainder was only offered on a separate disc through the by the franchise selected preferred chain store retailer Best Buy , a market discrimination strategy called the "retailer exclusive format", and one that is particularly loathed by fans and customers – especially by those who had only access to the "vanilla" releases.  At the time several scrupulous Best Buy patrons bought the Nemesis release in bulk and subsequently offered the special feature disc up at premium prices on eBay, the market site that was at the time rapidly becoming a force to be reckoned with. 
The following year, in 1999, the Star Trek television series premiered on DVD with the release of Star Trek: The Original Series in a two-episode-per-disc format, actually, and despite the far greater storage capacity of the new medium, in essence continuing the release format as utilized for the VHS predecessor. Like the films, essentially "vanilla" releases, these had virtually no bonus features to speak of, and were presented in a cardboard sleeve. The episodes were released in production order, with "The Cage" (in both black & white and colorized versions) being included on the final volume, and presented as a "bonus feature". These releases were Region 1 only; the rest of the world would have to wait until 2004 for an Original Series release, but they were spared the inefficient release format, as the new season box release format had by then become the norm – which irked American collectors who had invested in the "vanilla" release and who, after having replaced their Betamax/VHS collection, had to "double-dip" yet again to get the far superior box releases.
Left out of the original film "vanilla" release run, Paramount released Star Trek: The Motion Picture on DVD in 2001. For this release, the studio was persuaded to have the film reappraised as a whole, introducing new CGI visual effects, and re-cutting the film to better reflect Director Robert Wise's original intentions, resulting in that a theatrical cut of the film was not released on DVD until the 2009 Region 2 Star Trek: Original Motion Picture Collection. This "Star Trek: The Motion Picture (The Director's Edition)" was a two-disc release featuring for the first time extensive special features. These special features were produced by the DVD's co-producers David C. Fein and Michael Matessino, who actually were the pioneers of the phenomenon when their company Sharpline Arts produced these for popular genre films on the preceding LaserDisc format, much to the acclaim of collectors and film buffs. Building upon their experience gained, the ones on The Director's Edition were likewise favorably received by fans. Noteworthy was that it was this release that introduced Star Trek fans to the phenomena of text (written by "Treksperts" Mike and Denise Okuda) and audio commentaries, which went on to become a staple on subsequent DVD releases. The Director's Edition therefore became the first Star Trek DVD title to make the fullest use of the intrinsic qualities of the DVD format. While having received the blessing and support from Paramount Pictures, the studio has had itself no production input; rather the DVD project was an initiative of Robert Wise Productions, Wise's own production company, on the suggestion of Fein and Matessino under whose aegis the project was ultimately realized. (Star Trek: The Magazine Volume 2, Issue 8, p. 25) As such, Wise's company is the officially credited one, not Paramount whose role was limited to the distribution of the production – just like it had previously been for Star Trek: The Animated Series in the 1970s.
Following the enormous success of The Motion Picture Director's Edition however, Paramount was motivated to re-release the other nine prime universe films on their own accord in a similar fashion in the era 2002-2005 as the two-disc "special editions" collection – into which the originally intended stand-alone Director's Edition was retrofitted as the first one. As with the Director's Edition, these also included many newly produced special features (now primarily produced under the auspices of Patricia Rose Duignan, Donald R. Beck and Stephen R. Wolcott), along with the few ones that were previously featured on the "vanilla" releases, including those for Nemesis (which had been produced for the two year later release in this collection to begin with), redressing the perceived injustice as far as the fanbase was concerned, but still having to "double-dip" if they wanted the superior release. Various film collection box sets have followed suit in the wake of the original individual releases.
The next phase of Star Trek DVD releases saw the focus shift from individual volumes to season box sets for the television series. These box sets contained a decent number of special features (again produced under the aegis of Duignan, Beck and Wolcott), including documentaries, galleries and 'Easter eggs'. Each series would be released separately, with one series release finishing before the next would begin. The first series to receive the box set treatment was Star Trek: The Next Generation, which began its release in 2002. Star Trek: Deep Space Nine followed in 2003, with Star Trek: Voyager being released in 2004. A re-release of The Original Series in season box sets was intertwined with the Voyager release. The series release of Star Trek: Enterprise in 2005, saw audio commentaries, bloopers and deleted scenes additionally included as first-time special features on a series release. Over the years, several complete collections of all seasons were released as well, pursuant the original releases. The final series of the Roddenberry/Berman-era to be released was Star Trek: The Animated Series, which received a DVD release in late 2006.
In Region 2, two special box sets were released in 2003: the Star Trek: The Next Generation - Jean-Luc Picard Collection, and Star Trek: The Next Generation - The Complete TV Movies were unusual, in that they collected 'themed' episodes together – the latter also unusual in that it has yet to be released in Region 1. The sales of these led to Paramount announcing in 2005 that it was considering releasing DVD boxed sets containing episodes from any of the live-action Star Trek series, and polling fans via StarTrek.com as to the episodes to be released. The result of this was the Star Trek: Fan Collective box sets. The Collective releases were notable for several newly recorded audio commentaries and some especially produced production featurettes, most of these left out of the later released home media formats.
Following the success of the season box sets in Region 2, Paramount Home Entertainment chose to re-release the sets in new, "slimline" packaging at a much lower price – Next Generation in 2006, Deep Space Nine and Voyager in 2007, and Enterprise in 2008. In some territories such as Germany these were at first released as half-season sets though in Germany full-season sets were later made available in 2014.
In 2007, to celebrate the 20th anniversary of The Next Generation, a special complete series box set was released, containing the original discs released, plus a special retrospective bonus disc, the contents of the latter also left out of the later released home media formats.
The Original Series Remastered project saw the first release using next-generation optical media. The first season release in November 2007 was designed as a DVD/HD DVD combination, allowing it to be viewed on players of both formats. However, the collapse of the HD DVD industry in the wake of the format war with the Blu-ray format, meant that the remaining two seasons were released in DVD-only format throughout 2008, followed a year later by their Blu-ray counterparts.
Starting in 2009, the three alternate universe films started their release run, with the first one, Star Trek, becoming the last one to see both "vanilla" and "special" edition as of 2019. Concurrently, the ten original films saw the start of a re-release in the same year as remastered editions (the remastering actually done for their Blu-ray counterparts), featuring a selection of new special features as produced by Roger Lay, Jr. – actually also done for their Blu-ray counterparts, and which featured all special features, including the ones originally done for the "special editions" DVD collection, albeit in standard definition contrary to the new ones which were produced in high definition.
With the revival of the Star Trek television franchise in 2017, series releases started up again when Star Trek: Discovery saw its first season released on DVD in November 2018, alongside its Blu-ray counterpart, remarkably featuring the same amount of special features, constituting something of a break in release policies as the franchise had up to that point in time favored the Blu-ray format with the inclusion of more special features. Quite possibly this had been an intentional franchise attempt to avoid the 2014 "The VAM controversy" that had followed the home media format releases of the first two alternate reality films.
A popular feature in the early decades of the DVD had been the inclusion of so-called "Easter eggs", hidden special features, not accessible through the main DVD menu. Instead, these features had to be found by either entering a "secret" code on the remote control, or by searching for an Easter egg indicator on the menu graphic where a section would light up, indicating its presence. Typically these features were under five minutes shorts, usually comprised of cast and/or crew interview snippets, delving into subject matters not covered in the standard features. As far as Star Trek was concerned, the best known of these were the "Red Shirt Logs" on the Original Series season DVD releases, and the "Section 31 Files" on the Deep Space Nine season DVD releases. Some of the "special edition" Star Trek film DVD releases also contained Easter eggs, which were particularly hard to find. (X) Something of a fad at the time, the gimmick is losing its appeal in the Blu-ray Disc age, and in many cases the easily overlooked Easter eggs were not ported over to the Blu-ray counterpart re-releases, as had been the case with all of these from the Star Trek films.
Outside of film/series releases, DVDs are also used as components for board games. The game/toy companies Screenlife and Mattel co-released Star Trek Scene It?, an all-Trek edition of the trivia game series.
