From a teenager on a council estate in west London to self-made multimillionaire, Jamal Edwards hasn't done too badly for himself in a very short space of time.
Jamal is the owner of SBTV, a broadcasting company that makes videos - typically music videos featuring rap and pop music stars - and puts them up on YouTube.
It is not a bad living for a young man who got into film-making after his parents gave him a basic video camera as a Christmas present when he was 15, and someone who by his own admission has no formal training.
Back when Jamal was 15, he says he and his video camera immediately became inseparable, and he started to film friends rapping or singing.
Leaving school and getting a job in clothing company Topman, Jamal continued to make videos avidly in his spare time
Not instantly aware of the commercial potential of what he was doing, Jamal says he started to upload the videos to YouTube simply to make it easier for his extended friends to see them.
Building up a reputation for the quality of his work, he would film up-and-coming rappers and singers, while also targeting more established stars outside nightclubs, hotels and dance music radio station Kiss 100.
As word of mouth spread, his videos on YouTube, put up under the name SBTV (the SB stands for SmokeyBarz, Jamal's own rapping nickname) started to get hundreds of thousands of hits, predominantly from 13- to 30-year-olds.
And so Jamal contacted YouTube to see if he was eligible for a share of advertising revenues.
One of the thing Jamal said:
"I have crashed and burned about three times over the years because I was just working, working, working. Now I'm more planned, more organised"
And that's how he is working!
