Transfer Deadline Day, the most buzzworthy of football days in the media, sees hardcore fans glued to the feeds of Sky Sports News. To mark the importance of mobile comms in both negotiating and breaking the deals, the sports broadcaster has partnered with WhatsApp. The Facebook-owned messaging app sponsored the Transfer Deadline Day segments on live TV, further pushed on social. It is using the spot to highlight its View Once feature, an image that disappears after just a glance. Today, WhatsApp has been reacting to news breaking on the channel in real-time, solidifying the platform as the place to discuss the biggest moments in football. Social influencer Harry Pinero is leading the activity with a Transfer Deadline treasure hunt to look for clues, leads, predictions, opinions and exclusive behind-the-scenes news, all broadcast live near football stadiums in London. He’s being led by hints sent to his phone on WhatsApp using the View Once feature in a series of six vignettes.
