Notoriously publicity shy, Thylmann looks like an archetypal computer nerd: he is chubby, pale faced, sports thick glasses and jeans and likes wearing baggy tracksuit tops. His background and lifestyle betray little that would point to an individual committed to a life in porn. He is married with two children and lives a reclusive middle-class existence in Belgium, well removed from the prying eyes of Germany's Bild newspaper.
Born in Aachen, close to the border with Belgium, he moved to Brussels with his parents when he was a teenager and graduated at the city's international school. A job as a humble computer programmer followed. But within the past decade he has managed to revolutionise the entire business of pornography consumption and he has made online sex instantly available to all. Germany's Focus magazine referred to him recently as "The Ruler in the Realm of Lust".
Thylmann's online porn video empire is run by its parent company Manwin, which is the industry's global leader.
Using the same principle as YouTube, his websites allow visitors to watch pornographic videos for free. The income is generated by advertised sex pay sites that appear alongside and offer longer, full-length porn videos. An estimated 16 billion viewers click on to Manwin's sites every month. Only a fraction are reported to use the pay-for sites, but they are sufficient to bring in revenues in excess of €60 million each year.
Thylmann gave his first and only interview last year when he was sought out by journalists from the German edition of the Financial Times at a porn industry conference in Las Vegas. "Our objective is actually rather banal," he told them. "We want to create as many opportunities as possible for people to spend money."
He said he was glad to be interviewed because it "cleared up rumours" and "dispelled conspiracy theories" concerning his identity. Yet he was never heard of again until last week.
His breakthrough began in the late 1990s when he was still working as a computer programmer. Thylmann developed special computer software called Nats (Next-generation affiliate tracking software), which linked up the vast number of internet pornography sites for the first time and enabled visitors to select sex films according to personal preference. "Nats was very easy to use and could do what the others couldn't," Thylmann told Germany's FT.
The success of Nats encouraged Thylmann to start his own online sex sites, which are surfed by 60 million viewers a day.
The rise of YouPorn and similar sex sites has crippled the traditional porn industry, which relies on sex film cinemas, pornographic DVDs, magazines and sex shops, to generate income. If the complaints of those involved in the sex industry in famous locations such as Hamburg's famous Reeperbahn red-light district are to be believed, then virtual sex has also hit its real-life equivalent: prostitution. The Reeperbahn's last traditional brothel was forced to close down more than two years ago because of a dramatic drop in trade over the past decade.
By contrast, Thylmann's Manwin employs a staff of 1000 across the globe and has more than 35 subsidiaries in Luxembourg, Canada, Cyprus, Germany, the US, Britain and Ireland.
Thylmann denies that he avoided tax and maintains that he was merely minimising his tax burden in accordance with widely accepted practice. His lawyers will now have to convince German state prosecutors that there is no case to answer.
