A correction to the interview above is to be broadcast, saying: "In last week's programme we heard an interview with Kane Kramer, the man who invented the digital audio player. At the start of the programme we mentioned that Kane had in the past called himself "the world's biggest failure". He has asked us to explain that he didn't say that, and what he had said in the past was that 'it is one of the UK's biggest failures - I suppose in a way the world's biggest failure', and that he was talking about difficulties for inventors to get support."
This week's programme is an extended interview with the man who has in the past called himself "the world's biggest failure".
Kane Kramer devised the idea for the digital audio player back in 1979. It was the forerunner of the MP3 player today, but after problems with his company, Kramer's patents lapsed, and he has made little money from his invention.
Charles spoke to him at last week's Radio Reborn conference, and discusses his idea, but Kramer also explains how he is positive for the future of inventing (he is also the chairman of the British Inventors Society.
