The singing competition format sets out to find talented performers who can form a group for The Band, a Take That stage show that will run in the UK next year.
Take That singer and songwriter Barlow is a judge on the UK series alongside Danii Minogue and Martin Kemp, with Graham Norton and Mel Giedroyc the presenters.
BBC Worldwide was pitching the format to buyers at MIPTV and will now take the sales effort to Cannes.
Barlow will be in town to promote the event and attend a Let it Shine event, with live performances.
BBC Studios Entertainment Production made the eight-part UK show in association with Barlow and his fellow Take That members Mark Owen and Howard Donald.
BBCWW is the BBC’s commercial sales arm.
