For many years, there has been a discussion whether the old FM technology should be switched off. This is about the spread of HD-compatible radios compared to the classic FM radios and the online use for radio reception.
Each technology offers advantages and disadvantages. For radio operators it is also a question of cost if all three transmission paths are to be financed simultaneously.
In Europe, Norway has already discontinued FM transmission. In Switzerland, the time will soon come.
In Canada, the HD technology has started a few years ago with a testing phase but FM and AM radio is still very popular.
