IMDb (also known as the Internet Movie Database) is an online database, owned by Amazon, of information related to films, television programs, home videos, video games, and streaming content online – including cast, production crew and personal biographies, plot summaries, trivia, ratings, and fan and critical reviews. An additional fan feature, message boards, was abandoned in February 2017. Originally a fan-operated website, the database is owned and operated by IMDb.com, Inc., a subsidiary of Amazon.
As of January 2020, IMDb has approximately 6.5 million titles (including episodes) and 10.4 million personalities in its database, as well as 83 million registered users.
IMDb began as a movie database on the Usenet group “rec.arts.movies” in 1990 and moved to the web in 1993.
