This edition of the Fourth Estate looks at the legacy of Rupert Murdoch and Katharine Murphy's essay 'On Disruption'. We also look at Channel 7's 'racist' segment about African Gangs in Victoria, Fairfax's criticism of ABC's online news website and the appointment of Former News Corp CEO Peter Tonagh to run the Government's efficiency review on the public broadcasters ABC and SBS. To dissect this fractured media world, Josh Butler (Ten Daily) and Carrie Fellner (SMH) were in the studio and Corinne Podger (Melb Uni) on the line from the Southern Highlands. This episode was hosted and produced by Evie Maguire. Fourth Estate is produced by 2SER 107.3 in Sydney and is broadcast across the Community Radio Network in Australia.
