ITV3+1 is a channel which broadcasts in the UK on Freeview 58, Freesat 116, Virgin 174 and Sky 219.
It launched on 30th October 2006 alongside ITV2+1 and, as the name implies, broadcasts the output of ITV3 that had been shown one hour before. This means that each repeat of Coronation Street shown on that channel is also given another showing on the +1 channel.
