What does a technology correspondent do before he becomes a journalist?

Found an online network for the Jewish community? Launch a search engine for adult porn? Or both as Channel 4 News’ Benjamin Cohen did, starting out at the tender age of 16.

At 4pm (GMT) today on Radio 4, Cohen will discuss his dotcom past – including his stint as an unlikely porn baron and his sale of SoJewish to a newspaper, which he says wasted £1 million – in I Was a Teenage Dotcom Millionaire.

“In the programme he tracks down the investors who lost everything in his ventures and former employees to work out why things went so wrong,” says the blurb and there’s plenty more on Cohen’s whizzkid past – he was at one point higher than Prince William on the Sunday Times’ Rich List and also founded PinkNews.co.uk – in this Sunday Times’ interview.
