Lord David Puttnam retired from filmmaking almost 30 years ago due to the lack of integrity in the industry. He is currently in Australia where this week he addressed the Griffith Film School but he gave a speech which focused on the need for media regulation to curb the excesses of what he called ‘Data Capitalism’. For example, the personal data held by Sky TVof over 13 million British households is one of the largest and most sophisticated datasets in the country, but should Rupert Murdoch’s 21st Century Fox succeed in its take-over of Sky, David Puttnam fears this data trove could be used for political ends.
