BBC Radio 1 is a British national radio station operated by the British Broadcasting Corporation which also broadcasts internationally, specialising in current popular music and chart hits throughout the day. Radio 1 provides alternative genres after 7:00pm including electronic dance, hip hop, rock or interviews. It is aimed primarily at the 15–29 age group, although the average age of the audience is 33.

Radio 1 was established in 1967 (along with its somewhat more adult-oriented counterpart, BBC Radio 2) as a successor to the BBC Light Programme, which had broadcast popular music and other entertainment since 1945. Radio 1 was conceived as a direct response to the popularity of offshore pirate radio stations such as Radio Caroline, which had been outlawed by Act of Parliament. Radio 1 was launched at 7:00am on Saturday 30 September 1967.

Thomas William "Tom" Hiddleston (born 9 February 1981) is an English film, television, radio, and stage actor. He trained at the Royal Academy of Dramatic Art (RADA), and he rose to prominence through a number of TV roles and more recently major film roles. He played Loki in the 2011 Marvel Studios film Thor, Captain Nicholls in Steven Spielberg's World War I film War Horse (2011), and also Freddie Page in the British drama The Deep Blue Sea, alongside Rachel Weisz. He played author F. Scott Fitzgerald in the Woody Allen film Midnight in Paris (2011). He returned to his role as Loki in The Avengers (2012) and is set to reprise the character again for Thor 2 (2013).

Hiddleston was born in Westminster, London, to parents Diana Patricia (née Servaes), a former stage manager and arts administrator, and James Norman Hiddleston, a scientist in physical chemistry who was the managing director of a pharmaceutical company. His father is from Greenock, Scotland and his mother from Suffolk, England. He is the middle child with two sisters, Sarah (oldest), a journalist in India, and Emma (youngest), is also an actor. He was raised in Wimbledon, in his early years, and later in Oxford. When Hiddleston was 13, he boarded at Eton College, at the same time that his parents were going through a divorce. "I think I started acting because I found being away at school while my parents were divorcing really distressing." He went on to act at The Dragon School in Oxford, then continued on to the University of Cambridge, where he earned a double first. He graduated from the Royal Academy of Dramatic Art in 2005.
