The Internet Movie Database (abbreviated IMDb) was launched in 1990 by professional computer programmer Col Needham. It is now a commercial website owned by Amazon.com.
If you want to know information related to films, television programs and video games, (also including cast, production crew, fictional characters, biographies, plot summaries, trivia and reviews), you can use this free online database that is available to everyone. You can use the search bar to try and find what you are looking for.
The website allows visitors to share information about the movies, actors, directors and other insights they may have about films.
Users can rate any film on a scale of 1 to 10, and the totals are converted into a weighted mean-rating that is displayed beside each title, with online filters employed to deter ballot-stuffing. IMDb gives a good opinion of the general public since it has acquired a huge number of users over time.
The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others.
Users can create and maintain watchlists for the media they want to see later on. Additonally, users can make custom lists, listing various media as per their own preferences; these lists can then be made private or public for future references. Making IMDb is one of the best featues of the website as it has a good interface and a more professional understanding of database queries.
