Each year the ABC invites a prominent Australian to present the result of his or her work and thinking on major social, scientific or cultural issues in a series of radio talks known as the Boyer Lectures.This annual lecture began in 1959 and is named after the late Sir Richard Boyer, a former Chairman of the ABC. Over the years featured speakers have come from a very broad range of disciplines and interests. Previous Boyer lecturers include: former Reserve Bank Governor Ian Macfarlane, Archbishop Dr Peter Jensen, international affairs expert Owen Harries, historian Geoffrey Blainey, author David Malouf, former Prime Minister Bob Hawke, Aboriginal leader and lawyer Noel Pearson and Professor Graeme Clark AC. This year, Rupert Murdoch will illuminate our understanding of the rapidly changing media landscape, its impact on society today and in the future.
