Five's VoD service Demand Five has been made available to Mac and Linux users for the first time.

The broadcaster has launched a new version of the service utilising Flash media player technology. Previously Demand Five relied on Windows Media Player to serve video streams, meant it could only be accessed by PC users.

Five head of digital media Jonathan Lewis said: “Adopting Flash makes Demand Five accessible to more computers, more operating systems and consequently more users. It's the first of many upgrades we expect to make to the service over the next 12 months.”

Demand Five offers a 30-day catch-up service for both acquisitions such as CSI and Neighbours and commisssions including Fifth Gear and The Gadget Show.

It launched in July 2008 and now carries an archive of hundreds of hours of programmes from the past 12 months and beyond. It has also been available via BT Vision since October 2008.

Five has also announced that from 1 March its online video advertising sales, including Demand Five, will be handled by its in-house sales team.

Display advertising will continue to be sold by Five's digital agency Unanimus.
