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 by Alan Jay. Later, in 1993, it moved onto the fledgling World Wide Web under the name of Cardiff Internet Movie Database.[8] The database resided on the servers of the computer science department of Cardiff University in Wales.
