The BBC has announced the appointment of Matthew Postgate as chief technology officer.

He replaces John Linwood, who was sacked over the BBC's failed Digital Media Initiative (DMI) project.

Reporting to managing director of finance and operations, Anne Bulford, Postgate will be responsible for delivering a BBC technology strategy that covers the delivery and management of broadcast and enterprise technology infrastructure.

Postgate is currently the BBC's controller of R&D, where he is responsible for a number of teams working on innovation, internet technologies and operations. This includes a team that is delivering the world's first UHD (ultra high definition) broadcasts over internet protocol (IP) networks, including test screenings from the Brazil World Cup and Glasgow Commonwealth Games.

Bulford said: "Matthew knows technology, he knows the BBC and he knows how crucial this role is for the BBC. He has all the qualities needed to excel in this position and I know he will bring innovation, expertise and value to the BBC.

"I would also like to thank Peter Coles for his excellent stewardship of the team over the year as interim CTO."

Postgate said: "It's been a huge honour for me to lead a number of teams within BBC Future Media. They are the best in the business and leaders in their field, just look at the BBC's World Cup UHD trials, but opportunities like this are rare and I didn't want it to pass me by. I look forward to working with my new colleagues in Technology."

Postgate will start his role as CTO on 28 July.
