The primary use of a chat room is to share information via text with a group of other users. Generally speaking, the ability to converse with multiple people in the same conversation differentiates chat rooms from instant messaging programs, which are more typically designed for one-to-one communication. The users in a particular chat room are generally connected via a shared interest or other similar connection, and chat rooms exist catering for a wide range of subjects. New technology has enabled the use of file sharing and webcam to be included in some programs. This can be considered a chat room.
The first online chat system was called Talkomatic, created by Doug Brown and David R. Woolley in 1973 on the PLATO System at the University of Illinois. It offered several channels, each of which could accommodate up to five people, with messages appearing on all users' screens character-by-character as they were typed. Talkomatic was very popular among PLATO users into the mid-1980s. In 2014 Brown and Woolley released a web-based version of Talkomatic.
Chatroom is a 2010 British dramathriller film directed by Hideo Nakata about five teenagers who meet on the internet and encourage each other's bad behaviour. The film is based on the play Chatroom by Enda Walsh.
William Collins (Aaron Johnson) is a depressed teen recovering from self-harm and regularly goes online to chat rooms. One day, he decides to open a chat room himself and calls it "Chelsea Teens!" and where he meets Jim (Matthew Beard), another kid; Eva (Imogen Poots), a model; Emily (Hannah Murray), a goody two-shoes; and Mo (Daniel Kaluuya), a normal kid. There is no real subject matter in "Chelsea Teens!" which instead focuses on the lives of each teen as they talk. Even though they only really communicate through text, the film depicts them in an old hotel-like room and actually having contact.
