Fru Hazlitt, ITV managing director, commercial and online, is to step down after almost five years in the role.
Hazlitt's decision to stand down comes as her family have decided to relocate away from the UK for the next year.
“I have had a wonderful time at ITV,” said Hazlitt. “I’ve really enjoyed building a fresh team, transforming the Commercial side of the business and launching new revenue streams across advertising, pay, online and interactive. I work with extremely talented people and clients and I am very proud of all that we have achieved together.”
Adam Crozier, ITV chief executive, said Hazlitt had been a “terrific member of the management team” and praised her for doing a “fantastic job in transforming ITV’s commercial operation and building our online, pay and interactive business.”
He added: “She leaves with our thanks and very best wishes.”
Current joint commercial sales director Kelly Williams will step up to become managing director, commercial joining ITV’s management board and assuming responsibility for all of ITV’s commercial broadcast activities.
Online, pay and interactive are to be managed separately within the broadcast division to “give it even greater focus and momentum” according to Crozier.
In addition to management board responsibility for technology, Simon Pitt, current group director of strategy and technology, will become managing director online, pay and interactive.
Last year Hazlitt revealed to The Drum, as part of the Girl Guides series, what makes the UK’s most powerful content and marketing powerhouses tick.
