We have all become used to the idea that no news broadcast is complete without a ginormous iPad.
The ability to shift images and slides at the touch of a finger to the screen makes the TV presenter's gravitas just that much more gravitasy. It makes a Wolf just that much more Blitzer.
Yet, as this video first noticed by Videogum shows, not every TV presenter is a successful toucher and swiper.
This gentleman on a French-Canadian news channel suddenly finds that he wants to discuss troop movements in Gaza near elections, when his fingers cannot control chart movements near his nose.
What is lovely is that he carries on talking, while the information before him seems to be undergoing some sort of inner disturbance.
It slips, it slides, it twitches, it disappears.
Like a true professional, however, he marches on, as if nothing was untoward.
It could be that he'd had some particularly greasy fish and chips before his broadcast. It could be that the cleaners hadn't quite done a fine job of polishing the screen.
It might well be, though, that the technology he was using was just slightly the worse for wear.
If only he'd just talked to the camera and let someone else operate the screen. But that would have been too old-fashioned, wouldn't it?
