Byte Night is the IT industry's annual sleep out in support of Action for Children. Each year hundreds of individuals and teams from the technology and IT industries spend a night exposed to the elements in a bid to raise sponsorship and awareness of Action for Children's work. The event began ten years ago when 30 individuals from the IT industry slept out and raised £35,000. Since then the event has grown to extraordinary heights, attracting 270 sleepers and raising almost £400,000 in 2007 alone.
