ITV are switching off all their channels for one hour today to give you the opportunity to get out and get active with I Am Team GB. It could be the nation's biggest free sports day! Go to IAmTeamGB.com for more information. This is the 1 minute 30 second start and 30 second end of the hour of no programming across ITV's UK channels. I'm uploading this just for a few days for those that are interested! I believe, excluding strikes, this is the first time ITV has voluntarily shut down all it's channels, and all of them displayed these messages during 09:30 and 10:30 on Saturday 27th August on a repeated loop. Why not also take the time to try out a new sport in the wake of the Olympics!
