The appointment marks the first time News International has had a dedicated comms head, with its individual titles and parent News Corp formerly handling PR.
He will be pitched into the middle of the ongoing News of the World phone hacking saga. Reporter Clive Goodman and detective Glenn Mulcaire were jailed in January 2007, but recent reports have implicated more staffers, including then editor and current Conservative comms head Andy Coulson.
Greenberg was most recently chief of staff on the England 2018 World Cup bid, where he managed the comms, international relations, PR, marketing and public affairs for the bid.
Previously he was comms and public affairs director for Chelsea Football Club and has also worked as a journalist for The Evening Standard, the News of the World and The Mail on Sunday.
Greenberg said: ‘News International is one of the most dynamic companies in Britain and is at the forefront of the dramatic changes and challenges facing the media industry globally. To be asked to play a senior role in that is a great honour and I look forward to working with all the team in meeting those challenges.’
Brooks commented: ‘Simon has great experience at very high levels in professional sport and the media, making him ideal for this new and wide ranging corporate affairs role. I am delighted that he will be joining News International in such a senior capacity.’
