The Internet Movie Database (IMDb) is the largest, most comprehensive movie database on the web. It offers a comprehensive database of movie, TV show, and cast information. The site was officially launched in 1990 and is now owned by Amazon.com.

IMDb is an extremely detailed and rich source of movie data, featuring top movies, news, reviews, movie trailers, showtimes, dvd movie reviews, celebrity profiles and more. If you've ever researched a movie or actor, you've probably come across IMDb.

The site is truly a giant repository of movie information, and while it’s great that most of it is completely free to access, it can seem cluttered and difficult to navigate. Below are some tips on how to use IMDb, as well as a look at some of the features, including what you get with IMDbPro.

IMDb is, in short, extensive. It’s a huge hub of entertainment information. Virtually any search engine will point you there if you’re looking up the plot of a movie or trying to figure out who starred in a movie you just saw or who’s going to star in an upcoming TV show.
