To date, Byte Night has raised more than £500,000 for children's charity NCH, which runs projects throughout the UK aimed at ending youth homelessness.
The event involves more than just curling up in a sleeping bag with a hot water bottle. Participants will have plenty of opportunities to meet fellow IT bigwigs, and there will be plenty of entertainment on the evening, including games and live music.
In 2001, Byte Night attracted more than 100 top IT professionals from companies including Microsoft, ICL, RSA Security, and the Halifax.
John Cheney, managing director of managed security services firm Activis, who took part last year, says, "It is not often that you see direct action as part of a company's contribution responsibility. While many view managers as 'stuffed shirts', here is an example of people united in an effort to do some good."
It addition to the great and the good from the IT industry, Byte Night attracts a number of celebrities. Last year golfer Nick Faldo threw himself enthusiastically into all the night's events, despite being followed by a camera crew from a sports cable TV channel. Music was provided by upcoming singer Beverlei Brown.
Actress Jenny Agutter is a regular at Byte Night, and a long-time supporter of NCH. "Byte Night is about looking to the future," she said. "After all, IT is an industry about the future. It just shows we can do something that makes a difference."
This year Byte Night will take place on Friday 20 September in Finsbury Square, London. For further information or to register to be one of the sleepers contact Clare Caunt via email@example.com or 020-7704 7167 or go to www.bytenight.org.uk.
