The "sadistic exploitation" conducted by Robert Hunter, of Middlesbrough, was so extensive an international operation through Interpol was sparked.
This came after the 35-year-old had used sites such as Facebook, Skype and MSN to abuse girls as young as nine from across Europe, Asia, Canada and the US.
He would also often pose as the singer Justin Bieber in an attempt to convince the girls to expose themselves and perform sex acts on a webcam.
Teesside Crown Court heard that after being arrested in December 2012, he continued to target children and this resulted in a girl from Tasmania eventually contacting police, who traced him back to his home.
In total, more than 800 videos and images were discovered on his computer, all of them having been made by the defendant.
In total, Hunter pleaded guilty to 30 offences.
