Breen, who has been at the Telegraph for eight years, had only just been made sales director in September. In his new, broader role, he will combine the newspaper and online aspects of the Telegraph's business after a number of high-profile appointments over the last month.
Annelies van den Belt, the Telegraph Group's new-media director, said: "Ken's new post is a wider remit, putting requirements at the heart of the business to provide an integrated service and solutions for our advertisers and agencies."
There have been numerous changes within the Telegraph's online structure since the beginning of March, following the appointment of Edward Rousell as online editorial director. They include Julian Sambles as head of online operations and Sonia Sudhakar as head of online marketing.
The changes are part of the Telegraph's overall strategy to fully integrate its print and online editions.
Breen joined the Telegraph Group in 1998 from News Group Newspapers, where he was a sales executive on The Sun and News Of The World.
Dave King, Telegraph Group executive director, said: "Multimedia is here now and it's the future. We need multimedia practitioners. Ken's talent will be further utilised in this role."
