Life and Technology with Charlie Brown

Charlie Brown is one of Australia's cutting edge commentators on lifestyle technology. He is the technology editor for Channel Nine's Today Show and appears regularly on Nine News.

Charlie is able to communicate, educate and inspire a huge audience, without confusing technological jargon. Charlie's experience across a whole spectrum of media makes him the ideal person to go to when consumer electronics needs explaining in a clear, concise manner. In 2010, Charlie has been invited to participate in National Cyber Security Awareness Week 2010 by the Minister of Broadband, Communications and the Digital Economy, Senator Stephen Conroy, as an ambassador for the event.
