BBC Dorset FM was a BBC Local Radio station based in Dorchester, covering the county of Dorset in England which broadcast from 1993 to 1996. It was the last BBC Local Radio station to launch which covered a previously unserved area. It operated as an opt-out station from BBC Radio Devon for around 23 hours a week.
After 1993, there were no launches of BBC local radio stations that covered a previously unserved area.
BBC Dorset FM broadcast from 1993 to 1996 and was the last BBC Local Radio station to launch which covered a previously unserved area. So 1993 was the last year for such a launch. The algorithm missed this or misunderstood 'after'.
