History

Etymology

Coined by English astronomer Fred Hoyle on the BBC Third Programme, broadcast at 18:30 GMT on 28 March 1949. It is a popular but misinformed belief that this was intended as a derogatory term, Hoyle being a proponent of the opposing steady state theory, but Hoyle himself has rejected that notion.
