In the U.K. it’s still used to broadcast some national BBC stations (BBC R5 Live, BBC Asian Network) that aren’t available on FM and in some more areas it’s used to broadcast stations that are also on FM (BBC R4). They still also operate some LW! https://www.bbc.co.uk/reception/help-guides/fmmwlw-radio/fm-...

Until two weeks ago I used to listen to Absolute Radio in my car over MW but they shut it down.
