Channel 4's chief technology officer Bob Harris is leaving at the end of this month to set up his own consultancy to help companies deal with disruptive technologies, like the cloud.
Channel 4 was an early adopter of cloud services using Amazon Web Services (AWS), and is also a Hadoop big data analytics convert.
Channel 4 is using the scalability of cloud computing to handle a ten-fold growth in data, enabling the broadcaster to gain better insight into customer habits.
Harris's new business is Ethereality Associates. Harris told Computer Weekly: "Having joined Channel 4 in 1999 with a plan to stay for five years, it was time to move on.
"In reality, it's been a blast. In the early days we launched Big Brother with what were, at the time, unprecedented levels of web traffic and live video streaming."
Channel 4 also launched on-demand service 4oD in 2006, which is supported by AWS.
From 1 January, Harris told Computer Weekly, his technical responsibilities at Channel 4 were taken over by Orpheus Warr, who is Channel 4's chief architect and head of technical strategy.
