Man jailed in 'Hackerazzi' case
US District Judge James Otero sentenced Christopher Chaney in Los Angeles.
Chaney, 35, pleaded guilty to nine felony counts, including wiretapping and unauthorised access to a computer.
The biggest spectacle in the case was the revelation that nude photos taken by Johansson herself and meant for her then-husband Ryan Reynolds were placed on the internet.
Chaney also targeted women he knew, sending nude pictures of a former co-worker to her father.
He was arrested last year as part of a year-long investigation dubbed Operation Hackerazzi.
Prosecutors said Chaney illegally accessed the email accounts of more than 50 people in the entertainment industry.
