Network Ten has issued a statement to announce the resignation of its chief sales officer Barry O'Brien.
O’Brien had been in the role for only one year, succeeding predecessor Mike Morrison, who also resigned. His role will be taken up by national sales director Louise Barrett.
"We are extremely grateful to Barry for stepping in at a critical time for Network Ten. He was hired to stabilise and restructure Network Ten's Sales department, and to find a successor. He achieved those objectives, and more,” said Ten chief executive Hamish McLennan.
"Barry is one of Australia’s most experienced media executives. He has been a key member of Network Ten's executive team over the past 13 months and we wish him the very best for the future."
O‘Brien said: "I’ve worked with some great people here and we have a great team, including Louise Barrett, Kylie Rogers, Rod Prosser, Sarah Keith and others. I've achieved what I set out to do at Network Ten and the time is right to hand the reins to the next generation of executives."
