I'm always interested by strange technical faults on TV shows such as GMB and also channel breakdowns too. I decided it would be fun to make my own 'mock' if GMB went wrong video.
The audio from the presenter fades away and the headline bed starts playing again. There is also a persistent flicker - a black screen keeps reappearing. Audio also comes back for a split-second or two throughout. Perhaps this could be if there was some sort of interference with the broadcast, it's just for fun though, haven't really thought through the reason this could ever happen / if it would.
Very different to my 1st mock - hope you enjoy
