The Internet Movie Database (IMDb) is an online database of information about movies, actors, television shows, production crew personnel, and video games. IMDb launched on October 17, 1990, and in 1998 was acquired by Amazon.com.

Overview
The IMDb website consists of the largest accumulation of user-based data about films, television programs, direct-to-video products, and video games reaching back to each medium's respective beginning. In many cases, the information goes beyond simple title or press credits to include complete cast and crew credits, uncredited personnel, production and distribution companies, plot summaries, memorable quotes, awards, reviews, box office performance, filming locations, technical specs, promotional content, trivia, and links to official and other websites. Furthermore, the IMDb tracks titles in production, including major announced projects still in development. The database also houses filmographies for all persons, cast and crew, identified in listed titles. Filmographies include biographical details, awards listings, external links, and information about other professional work not covered by title entries in the database such as theatrical and commercial advertising appearances. The IMDb also offers ancillary material such as daily movie and TV news, weekly box office reports, TV listings, cinema showtimes, user polls and ratings, and special features about various movie events such as the Academy Awards. The website also has an active message board system. There are message boards for each database entry, found at the bottom of each respective page, as well as general discussion boards on various topics.
The IMDb is a free site, which requires registration to access its complete range of data and activities, although verification can sometimes require personal financial information such as credit card details. Any person with an e-mail account and a web browser that accepts cookies can set up an account with IMDb that allows them to submit information and engage in other site activities. As of Wednesday, Oct 10, 2007 imdb.com had 17,000,000 registered users.

In 2002, the IMDb spun off a private, subscription-funded site, IMDbPro, offering the entire content of the database plus additional information for business professionals, such as personnel contact details, titles in development, movie event calendars, and a greater range of industry news.
History
In rec.arts.movies
The database originated from two lists started as independent projects in early 1989 by participants in the Usenet newsgroup rec.arts.movies. In each case, a single maintainer recorded items emailed by newsgroup readers, and posted updated versions of his list from time to time. Google Groups coverage of rec.arts.movies is incomplete during the relevant time period, with a 6-month gap in late 1988 and early 1989 and a number of missing articles after that.
It began with a posting titled "Those Eyes", on the subject of actresses with beautiful eyes. Hank Driskill began to collect a list of sexy actresses and what movies they had appeared in, and as the size of the repeated posting grew far beyond a normal newsgroup article, it soon became known simply as "THE LIST".
The other project, started by Chuck Musciano, was briefly called the "Movie Ratings List" and soon became the "Movie Ratings Report". Musciano simply asked readers to rate movies on a scale of one to ten, and reported on the votes. He soon began posting "ballots" with lists of movies for people to rate, so his list also grew quickly.

Needham soon started a (male) "Actors List", while Dave Knight began a "Directors List", and Andy Krieg took over THE LIST, which would later be renamed as the "Actress List". Both this and the Actors List had been restricted to people who were still alive and working, but retired people began to be added, and Needham also started what was then (but did not remain) a separate "Dead Actors/Actresses List". The goal now was to make the lists as inclusive as the maintainers could manage.//groups.google.com/group/rec.arts.movies/msg/0203e8ba735348fd?dmode=source&hl=en|title= MRRLIST: Combined LIST & Movie Ratings Report|publisher=Google Inc.|accessdate=2007-01-15}}</ref> (His first posting of the database scripts is not available.)

The goal now was to make the lists as inclusive as the maintainers could manage. In late 1990, the lists included almost 10,000 movies and television series. On October 17, 1990, Needham posted a collection of Unix shell scripts which could be used to search the four lists, and the database that would become the IMDb was born. At the time, it was known as the "rec.arts.movies movie database".
On the web
By 1993, the database had been expanded to include additional categories of filmmakers and other demographic material, as well as trivia, biographies, and plot summaries; the movie ratings had been properly integrated with the list data; and a centralized email interface for querying the database had been created. Later in the year, it moved onto to the World Wide Web (a network in its infancy back then) under the name of Cardiff Internet Movie Database. The database resided on the servers of the computer science department of Cardiff University in Wales. Rob Hartill was the original web interface author. In 1994, the email interface was revised to accept the submission of all information, meaning that people no longer had to email the specific list maintainer with their updates. However, the structure remained that information received on a single film was divided among multiple section managers, the sections being defined and determined by categories of film personnel and the individual filmographies contained therein. Its management also continued to be in the hands of a small contingent of underpaid or volunteer "section managers" who were receiving ever-growing quantities of information on films from around the world and across time from contributors of widely varying level of expertise and informational resources. Despite the annual claims of Needham, in a year-end report newsletter to the Top fifty contributors, that "fewer holes" must now remain for the coming year, the amount of information still missing from the database was vastly underestimated. Over the next few years, the database was run on a network of mirrors across the world with donated bandwidth.
As an independent company
In 1995, it became obvious to the principal site managers that the project had become too large to maintain merely through donations and in their spare time. The decision was made to become a commercial venture and in 1996, IMDb was incorporated in the United Kingdom, becoming the Internet Movie Database Ltd, with Col Needham the primary owner as well as identified figurehead. The remaining shareholders were the people maintaining the database. Revenue was generated through advertising, licensing and partnerships.
This state of affairs continued until 1998. The database was growing every day, and it was again reaching a critical point. Most revenues were being spent on equipment, and there was not enough money left over to pay full time salaries. The system was also suffering noticeable slowdowns both in accessing the site and in having new data posted. Offers were solicited and received from major businesses to purchase the database; however, the shareholders were unwilling to sell if it could not be guaranteed that the information would be accessible to the internet community for free.

TV episodes
On 26 January 2006, the long-awaited "Full Episode Support" came online, allowing the database to support separate cast and crew listings for each episode of every TV series. This was described by Col Needham as "the largest change we've ever made to our data model," and increased the number of titles in the database from 485,000 to nearly 750,000.
At present, the database entries for TV series are in a state of flux, as listings are migrated from series titles to individual episodes. The maintainers anticipated "a couple of months for data to settle down and bugs to be ironed out", but inaccuracies were still present one year later.

Ancillary features
User ratings of films
As one adjunct to data, the IMDb offers a rating scale which allows users to rate films by choosing one of ten categories in the range 1–10, with each user able to submit one rating. The points of reference given to users of these categories are the descriptions "1 (awful)" and "10 (excellent)"; and these are the only descriptions of categories. Due to the minimum category being scored one, the mid-point of the range of scores is 5.5, rather than 5.0 as might intuitively be expected given a maximum score of ten. This rating system has also recently been implemented for television programming on an episode-by-episode basis.
In adopting this method, IMDb is following its widespread usage; the method is the same as rating in the range of a half star to five stars. When used in reviews by a single reviewer, the method has some basic utility given a rating is usually given in the context of a qualitative appraisal of the film. The simplicity of this method makes it popular, but in terms of psychometric, statistical, and other criteria, the method suffers shortcomings (see online rating scales).
Filters and weights
IMDb indicates that submitted ratings are filtered and weighted in various ways in order to produce a weighted mean that is displayed for each film, series, and so on. It states that filters are used to avoid vote stuffing; the method is not described in detail to avoid attempts to circumvent it.

where:
- <math>W\ </math> = Weighted Rating
- <math>R\ </math> = average for the movie as a number from 0 to 10 (mean) = (Rating)
- <math>v\ </math> = number of votes for the movie = (votes)
- <math>m\ </math> = minimum votes required to be listed in the Top 250 (currently 1300)
- <math>C\ </math> = the mean vote across the whole report (currently 6.7)
An extended listing of the Top 500 - following the same formula - is available to IMDbPro subscribers.

The top 250 list comprises a wide strata of films, including major releases, cult films, independent films, critically acclaimed films, silent films and foreign films.

Message boards
One of the most used features of the Internet Movie Database is the Message Boards that coincide with every title (excepting TV episodes) and name entry, along with forty-seven Main Boards. These boards allow registered users to share, discuss and debate information about the movie and/or people that worked on it. They were not originally part of the IMDb, but were added only after its purchase by Amazon.com, some time in the year 2000.

Copyright issues
All volunteers who contribute content to the database retain copyright to their contributions but grant full rights to copy, modify, and sublicense the content to IMDb.
Foreign-language films
The Internet Movie Database is written completely in English (although it does have sister websites in www.imdb.com/widgets/ the IMDb List Widget]//finnish.imdb.com/ Finnish], www.imdb.com/widgets/ the IMDb List Widget]//french.imdb.com/ French], www.imdb.com/widgets/ the IMDb List Widget]//german.imdb.com/ German], www.imdb.com/widgets/ the IMDb List Widget]//hungarian.imdb.com/ Hungarian], www.imdb.com/widgets/ the IMDb List Widget]//italian.imdb.com/ Italian], www.imdb.com/widgets/ the IMDb List Widget]//polish.imdb.com/ Polish], www.imdb.com/widgets/ the IMDb List Widget]//portuguese.imdb.com/ Portuguese] (and www.imdb.com/widgets/ the IMDb List Widget]//brazilian.imdb.com/ Brazilian Portuguese]) , www.imdb.com/widgets/ the IMDb List Widget]//romanian.imdb.com/ Romanian] and www.imdb.com/widgets/ the IMDb List Widget]//spanish.imdb.com/ Spanish]). Despite this, IMDb lists the titles of foreign-language films in their www.imdb.com/widgets/ the IMDb List Widget]//www.imdb.com/help/show_leaf?akas original language]. This requires English-speaking users to search far down the front-page listing for a film, into the "Additional Details" section, just as non-English speakers must do for English titled films. For example, the Japanese anime film Spirited Away is www.imdb.com/widgets/ the IMDb List Widget]//www.imdb.com/title/tt0245429/ listed] as Sen to Chihiro no kamikakushi, the original Japanese title, and English-speaking readers must look down below the cast list to find the English title. English-speaking users browsing IMDb's www.imdb.com/widgets/ the IMDb List Widget]//www.imdb.com/chart/top Top 250 list] must click the listing for Wo hu cang long to discover that that film is Crouching Tiger, Hidden Dragon.
