Chief commercial officer, Sophie Moloney, is Sky Network Television Limited’s new chief executive.

Moloney replaces Martin Stewart who is leaving the company to return home to Europe. Stewart has been with Sky for 21 months.

He took over from long-time company boss John Fellet and was given the job of shifting the business from a traditional satellite pay TV operation to a multi-platform business geared for the fibre era.

During Stewart’s time with Sky the pay TV company announced it would become a broadband service provider.

Before taking over at Sky, Stewart was CEO of OSN, a Dubai-based organisation. There he oversaw its adoption of a new digital platform and worked on updating the company’s digital infrastructure. Earlier he was chief financial officer at BSkyB in the UK.

Moloney has a 20-year track record in the media sector. She also worked at OSN in Dubai and with Sky in the UK.

Sky Chair Philip Bowman says Maloney’s recent achievements include: "securing the commercial agreement with Spark to secure Rugby World Cup Rights for pubs and clubs around New Zealand, leading the team that secured New Zealand Rugby and SANZAAR rights, negotiating the new Optus satellite agreement and spearheading Sky’s purchase of entertainment streaming service Lightbox.”
