channel

( n.)

   [IRC]  The  basic  unit  of  discussion  on  {IRC}.  Once one joins a
   channel,  everything  one  types  is  read by others on that channel.
   Channels  are  named  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,
   callahans, 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).
