The Free On-line Dictionary of Computing (19 January 2023):

channel
chat room
room

    (Or "chat room", "room", depending on the system in
   question) The basic unit of group discussion in chat systems
   like IRC.  Once one joins a channel, everything one types is
   read by others on that channel.  Channels can either be named
   with numbers or with strings that begin with a "#" sign and
   can have topic descriptions (which are generally irrelevant to
   the actual subject of discussion).

   Some notable channels are "#initgame", "#hottub" and
   "#report".  At times of international crisis, "#report" has
   hundreds of members, some of whom take turns listening to
   various news services and typing in summaries of the news, or
   in some cases, giving first-hand accounts of the action
   (e.g. Scud missile attacks in Tel Aviv during the Gulf War in
   1991).
