Wheldon was a BBC Broadcaster and Executive. He was knighted in 1976. Following his retirement from the BBC he became Chairman of the Court of the Governors of the London School of Economics, where he had read economics before the war. He disarmed potential sponsors of the school by eschewing flattery and opening negotiations with the bald statement that what he was after was their cash. He was also a formidable and active President of the Royal Television Society (RTS). An RTS Memorial Lecture in his name by a distinguished broadcaster is televised annually.
Sir Huw’s lasting influence, other than as a programme maker, which was considerable, probably lies in the ways in which he articulated the needs and requirements of public service broadcasting. “To make the good popular and the popular good”, “the aim is not to avoid failure, but to attempt success”, “multiplicity does not mean choice”, were among his favourite sayings. He also coined the term “narrowcasting”.
