Channel 4 has made changes to its senior management team, including an expanded remit for sales director Jonathan Allen. Allen, who was appointed sales director in September 2011, will be given responsibility for all revenue earning activity.

Director of commercial affairs, Martin Baker, will join the executive team and will now represent legal and compliance and 4Rights, in addition to his current role.

Finance director Glyn Isherwood has become group finance director and will also join the executive team. Meanwhile, Keith Underwood, currently director of strategy, will join the executive team as director of strategy and technology.

David Abraham, Channel 4 chief executive, said: “One of the great strengths of Channel 4 is the breadth of talent we have within what is a small organisation when compared to some of our competitors. We have always been committed to developing that talent, and last year introduced a programme specifically aimed at growing our senior managers to become leaders of the future.

With this in mind, I have reviewed how we work and I am delighted to be able to announce a number of changes which promote key staff to the executive team in newly created roles and expands the team of talented people we can bring to major creative and commercial decision making.”
