Russell Davies presents a tribute to Reginald Fessenden, the first voice of broadcasting, in a sound chronicle of the century that has passed since.
He recalls the very first radio programme, which was broadcast on Christmas Eve 1906.
It was produced and presented by Fessenden, a Canadian engineer who was working on a radio transmitting station he had built at Brant Rock, just outside Boston, Massachusetts.
The broadcast consisted of a violin solo, a Bible reading, a gramophone record and a short speech and was picked up by some very startled radio operators on suitably equipped ships at sea.
The same programme was broadcast again on New Year's Eve, so that the first-ever radio broadcast in the line of entertainment became the first repeat.
