Channel ☺+1

Channel ☺+1. (DW: The Long Game)

Channel ☺+1 was one of the six hundred channels broadcast by Satellite Five in 200000. When the Ninth Doctor, Rose Tyler and Adam Mitchell arrived on the station that year, Channel ☺+1 was seen reporting solar flare activity. (DW: The Long Game)

By its name, this channel was presumably the timeshift channel of a "Channel ☺", outputing exactly the same programming as was broadcast an hour previously on its parent channel.
