On Thursday 5 March 2020 Smithsonian Channel will be making changes to the way it's broadcast.

If you've been viewing Smithsonian on channel 99 or channel 793, this will no longer be available - to continue receiving you'll need to do a quick retune to find it at its new home on channel 57.

You may need to retune to update your TV to keep your TV Guide up to date. To find out more about retuning watch our handy retune videos.
