Which is why:
"ITV is switching off all seven of its channels for an hour to encourage people to get off their sofas and take part in sport following Team GB's Olympics success.
ITV will stop broadcasting from 09:30 on 27 August as part of the I Am Team GB campaign.
The move, organised with the National Lottery, will also see thousands of sports clubs open to let people try new sports for free.
Olympic medallists, including long jumper Greg Rutherford, will take part.
The Bank Holiday weekend event is part of the celebrations to welcome home Team GB from the Rio Olympics."
