When he was 15-years-old Jamal Edwards started filming his friends on a camera he was given for Christmas.
By 22 he had his own broadcasting company worth £8 million and a place on the Sunday Times rich list.
Jamal who is about to publish his first book, told BBC Breakfast that his success is down to the fact that he was consistent and had a niche.
"There's probably a thousand other people who are filming as well but i did it in a different way... I never got complacent," he said.
